The gas phase decomposition \[2{{N}_{2}}{{O}_{5}}\to 4N{{O}_{2}}+{{O}_{2}}\] follows the first order rate law. \[K=7.5\times {{10}^{-3}}{{\sec }^{-1}}\]. The initial pressure of \[{{N}_{2}}{{O}_{5}}\] is 0.1 atm. The time of decomposition of \[{{N}_{2}}{{O}_{5}}\] so that the total pressure becomes 0.15 atm will be
