4. The decomposition of NO follows a second order rate equation. The forward reaction (2N20 2Nz + Os) has a specific reaction rate k = 980 cm/gm mole sec at 900PUC. Calculate the fraction decomposed at 1 sec, 10 sec and 10 min in a constant volume batch reactor. Assume the rate of reverse reaction to be negligible and the initial pressure 1.0 atm. (5) 3
