question_answer

For a zero order reaction, the plot of concentration of reactant vs time is (intercept refers to concentration axis)

A) linear with +ve slope and zero intercept

B) linear with -ve slope and zero intercept

C) linear with -ve slope and non-zero intercept

D) linear with +ve slope and non-zero intercept

E)  a curve asymptotic to concentration axis

Correct Answer: C

Solution :

For a zero order reaction, the plot of concentration of reactant\[vs\]time is a straight line (linear) with a negative slope and non-zero intercept.
