Question

Consider the 2-step reaction mechanism
fast 2NO + H2 $ N2O+H2O
slow N2O+H2 ! N2+H2O
net 2NO + 2H2 ! N2 + 2H2O
Which of the following rate laws is cor-
rect for the given mechanism? Note that the
constant k may represent a combination of
elementary reaction rate constants.

Answer 1

Which of the following rate laws is cor-
rect for the given mechanism?

You have not shown any rate laws.

Answer 2

the rate law choices are:
1. rate in respect to net=k[NO][H2]
2. rate net=k[NO]^2[H2]^2
3. rate net=k([H2]^2[NO]^2)/[H2O]
4. rate net=k[NO]^2[H2]
5.rate net=k([N2][H2O]^2[H2]^2)/[NO]^2

please help! :)
