The gaseous decomposition reaction, A(g)rarr2B(g)+C(g) is observed to first order over the excess of liquid water at 25^(@)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 hr^(-1)) is : [Given : vapour pressure of H_(2)O at 25^(@) is 28 torr (ln2=0.7, ln3=1.1, ln10=2.3)] |
