The rate constant for the reaction,  \[2{{N}_{2}}{{O}_{5}}\to 4N{{O}_{2}}\]\[+{{O}_{2}}\] is \[3\times {{10}^{-5}}{{\sec }^{-1}}\]. If the rate is \[2.40\times {{10}^{-5}}mol\,\,litr{{e}^{\text{-1}}}{{\sec }^{-1}}\]. Then the concentration of \[{{N}_{2}}{{O}_{5}}\](in mol litre-1) is [IIT Screening 2000]
