Question

The decomposition of NH₃ on platinum surface is zero order reaction. If k = 2.5 × 10⁻⁴ mol L⁻¹ s⁻¹ what are the rates of production of N₂ and H₂?

In a given graph of zero order reaction, the slope and intercept are :

Assertion (A) : The units of rate constant of a zero order reaction and rate of reaction are the same. Reason (R) : In zero order reaction, the rate of reaction is independent of the concentration of reactants.

(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?
