Question

Half life of a chemical reaction at a particular
oncentration is 75 minute. When the
concentration of the reactant is doubled, the half
life becomes 150 minute. What is the order of
reaction?
(1) First order
(2) Zero order
(3) Second order (4) Third order
​

Answer 1

Answer:

2. is correct answer

Explanation:

In zero order reaction half life is directly proportional to concentration

$half \: life = \frac{a}{2k}$
