Question

If the initial concentration of reactants in the certain reaction is double, the half-life period of the reaction doubles, the order of a reaction is:

• A. Zero
• B. First
• C. Second
• D. Third

Answer 1

The correct option is A Zero

As we know,
For zero order reaction
$t_{1/2}\propto (a{)}^{1-n}$
$t_{1/2}\propto (a{)}^1$
