Hi everyone
At the present Iam working on, Elementary Reaction. However,Iam facing some difficulties about How can made rate of reaction equation from elementary kinetics such as :
Water Gas Shift
K1
H2O + M ----------- H + OH + M

K-2 K2
CO + OH --------------------- H + CO2

K-3 K3
H2O + H -------------------- OH + H2

K-1
H + OH + M------------------- H2O + M

How can I get on this equation from above elementary reaction ?

d[CO2] K1 * K2 * K3
r =------------=( --------------- )^0.5 * [CO]^0.5 *[H2O]
dt K-1


I would be very grateful if anyone would tell me about that.

Thank you
