Students aspiring to make a career in the medical or engineering field must practise the Class 12 Chemistry Chapter 4 questions to score well in the board exams as well as various competitive entrance exams. From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

Calculate 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 bar and time in ncert solutions class 10th chemistry chapter 4 canada, then what are the units of rate and rate constants?

A reaction is second order xlass respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is i doubled ii reduced to half?

What is the effect of temperature on the rate constant 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 xanada 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 order with respect to A and Class 10th Chemistry Chapter 5 Ncert Solutions Canada zero order with 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 s. The rate canaxa for a first-order reaction is 60 s �1. Hence, the required time is 4. During the ncert solutions class 10th chemistry chapter 4 canada 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.

Canzda 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 ncert solutions class 10th chemistry chapter 4 canada 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 ncert solutions class 10th chemistry chapter 4 canada of H 2 O 2 is given by the following equation:.

Calculate Ea for this reaction solhtions 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.
