QAIPMT-2004-Ch-2612: NEET 2004 Chemistry - Class 12 AIPMT-2004-Ch-2612 Solution: The rate of a first order reaction is \(1.5 10^{-2}\ {mol…

The rate of a first order reaction is

1.5\times10^{-2}\ \text{mol L}^{-1}\ \text{min}^{-1}

at 0.5 M concentration of the reactant. The half-life of the reaction is

Step-by-Step Verified Solution

For a first order reaction, A _ products Rate(r) = k[A] _ k = r [ A ] _ k = 1.5 _ 10 _ 2 0.5 = 3 _ 10 _ 2 So, t 1 / 2 = 0.693 3 _ 10 _ 2 = 23.1 min
