The gaseous decompostion reaction, \[A\left( g \right)\to 2B\left( g \right)+C\left( g \right)\] is observed to first order over the excess of liquid water at \[25{}^\circ C\] . It is found that after 10 minutes the total pressure of system is 188 torr and after very long time it is 388 torr. The rate constant of the reaction \[(in~h{{r}^{-1}})\] is: [Given: vapour pressure of \[{{H}_{2}}O\] at \[25{}^\circ \] is 28 torr (In 2=0.7, in 3=1.1, in 10=2.3)]
