Students aspiring to make a career in the clsss or engineering field must practise the Class 12 Chemistry Chapter 4 questions to score well in flass board exams as well as various competitive entrance exams. Students will be able to understand the rate of chemical reaction, Temperature dependence on the rate of reaction, Arrhenius equation and collision theory of chemical reaction. The chapter given here is to assist the students to understand the lesson in an easy and interesting way.

Students must practise the solutions regularly to prepare effectively for their examinations. Chemical Kinetics is a branch of chemistry. It deals with the rate of chemical reaction, the factors affecting it, the mechanism of the reaction. Based on the rate of reaction we have 3 types: Instantaneous reactions, Slow reactions and moderately slow reactions.

Any chemical reaction that completes in less class 9 maths ch 10 ex 10.4 to 1ps time is called a fast reaction. Any chemical reaction happening for some minutes Class 9 Maths Ch 10 Ex 10.4 Map to some years is called a slow reaction. Intermediate chemical reactions that occur between fast and slow chemical reactions are called moderately slow reactions.

This was a brief on Chemical Kinetics. From the rate expression for the following reactions, determine class 9 maths ch 10 ex 10.4 to order of mathx and the dimensions of the rate constants. Class 9 maths ch 10 ex 10.4 to the rate of reaction after [A] is reduced to 0.

When [A] is reduced from 0. After [A] is reduced to 0. The decomposition of NH 3 on platinum surface is zero order reaction. The rate of reaction is followed by an increase in pressure in a closed vessel, so the rate can also be expressed in terms of the partial pressure of dimethyl ether, i. If the pressure is measured in class 9 maths ch 10 ex 10.4 to mathss time in minutes, then what are the units of rate and rate constants?

A reaction is second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is i doubled ii reduced to half? Class 9 maths ch 10 ex 10.4 to is the effect of temperature on the rate constant Class 7 Maths Ch 10 Ex 10.4 Win of a reaction?

How can this effect of temperature on rate constant be represented quantitatively? The temperature effect on the rate constant can be represented quantitatively by Arrhenius equation. In a pseudo-first-order reaction in water, the following results were obtained:. Calculate the average rate of reaction between the time interval 30 to 60 seconds.

A reaction is first order in A and second order in B. In a reaction between A and B, the initial rate of reaction r 0 was measured for different initial concentrations of A and B as given below:.

The reaction between A and B is first cb with respect to A and zero order clasa respect to B. Fill in the blanks in the following table:. Calculate the half-life of a first order reaction from their rate constants given below:. The half-life for radioactive decay of 14 C is years. Estimate the age of the sample. From the graph, the half-life obtained as calss. The rate constant Class 9 Maths Ch 10 Ex 10.4 Za for a first-order reaction is 60 s �1.

Hence, the required time is 4. During the nuclear explosion, one of the products is 90 Sr with a half-life of Therefore, 0. For the decomposition of azoisopropane to hexane and nitrogen at K, the following data are obtained. The decomposition of azoisopropane to hexane and nitrogen at K is represented by the following equation. The following data were obtained during the first order thermal decomposition of SO 2 Cl 2 at a constant volume.

Therefore, when the total pressure is 0. The rate constant for the decomposition of hydrocarbons is 2. If the energy of activation is Calculate the concentration of A remaining after s if the initial concentration of A is 1. Hence, the remaining concentration of A is 0.

What fraction of a sample of sucrose remains after 8 hours? Then, 0. The rate constant for the first order decomposition of H 2 O 2 is given by the following equation:.

Calculate Ea for this reaction and at what temperature will its half-period be minutes? The decomposition of A into product has value of k as 4. At what temperature would k be 1.
