Question

When the initial concentration of the reaction is doubled, the half-life is also doubled. The order of the reaction will be:

• A. $0$
• B. $1$
• C. $2$
• D. $3$

Answer 1

The correct option is A $0$

Half life $\alpha$ initial concentration

This corresponds to zero order reaction where $t_{1/2}=\frac{a}{2k}$
