An experiment tells us that the following reaction is first order with respect to He and third order with respect to NO.
2NO(g) + 2H2 (g) N2 (g)+ 2H20 (g)
We also know that the rate constant for this reaction is 6.00 x 105 1/M-sec at 1280 °C.
What is the instantaneous rate for this reaction at 1280 °C if the initial concentration of Hz is
1.65 M and the initial concentration of NO is 0.895 M?
