Question

Consider the following first order gas phase reaction at constant temperature ( A ( g ) 2 ~B ( ~g )+ C ( g ) ) If the total pressure of the gases is found to be 200 torr after (23 sec ). and 300 torr upon the complete decomposition of A after a very long time, then the rate constant of the given reaction is ______ ( 10⁻² ~s ⁻¹ ) (nearest integer) [Given : ( ₁₀(2)=0.301 )]
