For the reaction, 2NO+H2→N2O+H2O the value of -dp/dt is found to be 1.50Torrs−1 for a pressure of 359 Torr of NO and 0.25Torrs−1 for a pressure of 152 Torr, the pressure of H2 being constant. On the other hand, when the pressure of NO is kept constant, \dp/dt is 1.60Torrs−1 for a hydrogen pressure of 289 Torr and 0.79Torrs−1 for a pressure of 147 Torr. The over all order of the reaction is :

Answer» For the reaction, $2 N O + H_{2} \to N_{2} O + H_{2} O$ the value of -dp/dt is found to be $1.50 T o r r s^{- 1}$ for a pressure of 359 Torr of $N O$ and $0.25 T o r r s^{- 1}$ for a pressure of 152 Torr, the pressure of $H_{2}$ being constant. On the other hand, when the pressure of $N O$ is kept constant, \dp/dt is $1.60 T o r r s^{- 1}$ for a hydrogen pressure of 289 Torr and $0.79 T o r r s^{- 1}$ for a pressure of 147 Torr. The over all order of the reaction is :
