Rate of a first order reaction is 1.5 10⁻² ~mol ~L ⁻¹ minute ⁻¹ at 0.5 M concentration of reactant, calculate half life of reaction.

Step-by-step solution

array ll & For a 1^ st order reaction, & Rate = k ( A )^1 & 1.5 10⁻² ~mol ~L ⁻¹ minute ⁻¹= k (0.5 M ) k =0.03 minute ⁻¹ array t _ 1 / 2 = 0.693 0.03 minute ⁻¹ =23.1 minute
