Question
The decomposition reaction 2N2O5(g)Δ−→2N2O4(g)+O2(g) is started in a closed cylinder under isothermal isochoric condition at an initial pressure of 1 atm. After Y×103s, the pressure inside the cylinder is found to be 1.45 atm. If the rate constant of the reaction is 5×10−4s−1, assuming ideal gas behaviour, the value of Y is
