Question

For a zero order reaction of the type A → products, the rate equation may be expressed as :

Answer the following questions (Do any two) : (a) Identify the order of reaction from the following unit for its rate constant : Lmol⁻¹s⁻¹ (b) The conversion of molecules A to B follow second order kinetics. If concentration of A is increased to three times, how will it affect the rate of formation of B? (c) Write the expression of integrated rate equation for zero order reaction.

(a) The variation in the concentration (R) vs. time (t) plot is given below. Answer the following questions on the basis of the given figure: (i) Predict the order of the reaction. (ii) What is the slope of the curve? (iii) What are the units of the rate constant k?

The rate constant for a zero order reaction A → P is 0.0030 mol L⁻¹s⁻¹. How long will it take for the initial concentration of A to fall from 0.10 M to 0.075 M?
