The following reaction is first order with respect to NO and first order with respect to O2, and the rate constant is 5.0 x 104 M-1s-1:
2NO(g) + O2(g) --> N2O4(g)
a) Write the rate law for this reaction.
b) What is the rate of the reaction when [NO] = 0.125 M and [O2]=0.250 M?
c) What is the overall reaction order?
