Question

For a certain reaction, a plot of $\frac{[C_0-C]}{C}$ against time $t$, yields a straight line. $C_0$ and C are concentration of reactant at $t=0$ and $t=t$ respectively. The order of reaction is:

• A. $3$
• B. $0$
• C. $1$
• D. $2$

Answer 1

The correct option is D $2$

As we know, for II${}^{nd}$ order reaction: $\frac{C_0-C}{C_0}=K\cdot t\cdot c$.
So order of reaction is 2${}^{nd}$.
