Question

The gaseous decomposition reaction, $A(g)⟶2B(g)+C(g)$ 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 $(\ln 2=0.7,\ln 3=1.1,\ln 10=2.3)$ ]
