The gaseous decomposition reaction,
A(g) `rarr` 2B(g) + C(g)
is observed to be first order over the excess of liquid water at `25^(@)C`. If is found that after 10 minutes the total pressure of system is 188 torr. The rate costant of the reaction (in `hr^(-1)) is :
[Given : vapour pressure of `H_(2)O` at `25^(@)` is 28 torr `("ln" 2=0.7,"ln"3=1.1,"ln"10=2.3)`]
A. `0.02`
B. `1.2`
C. `0.2`
D. none of these
