Q57. Consider the following first order gas phase reaction at constant temperature $\mathrm { A } ( \mathrm { g } ) \rightarrow 2 \mathrm {~B} ( \mathrm {~g} ) + \mathrm { C } ( \mathrm { g } )$ 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 $\_\_\_\_$ $\times 10 ^ { - 2 } \mathrm {~s} ^ { - 1 }$ (nearest integer) [Given : $\log _ { 10 } ( 2 ) = 0.301$ ]
