The decomposition of \[{{N}_{2}}{{O}_{5}}\] is a first order reaction represented by \[{{N}_{2}}{{O}_{5}}\to {{N}_{2}}{{O}_{4}}+\frac{1}{2}{{O}_{2}}\]. After 15 minutes the volume of \[{{O}_{2}}\] produced is \[9\,ml\] and at the end of the reaction \[35\,ml\]. The rate constant is equal to [MP PET 1995]

A)   \[\frac{1}{15}\,\ln \,\frac{35}{44}\]       

B)   \[\frac{1}{15}\,\ln \,\frac{44}{26}\]

C)   \[\frac{1}{15}\,\ln \,\frac{44}{35}\]       

D)   \[\frac{1}{15}\,\ln \,\frac{35}{26}\]
