Chemical Kinetics Part 2

Consider the following first order gas phase reaction at constant temperature
A(g)⟶2B(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 : log10(2)=0.301]
