Question

For a general reaction A → B, plot of concentration of A vs time is given in figure. Answer the following question on the basis of this graph.

(i) What is the order of the reaction?

(ii) What is the slope of the curve?

(iii) What are the units of rate constant?

Short/Brief Note

Solution

(i) Zero order reaction

(ii) [R] – [R]0 – kt

∴ Slope = – k

(iii) `(mol^-1L)/(s^-1)` = k[A]0 or k = mol–1 Ls–1
