Order of reaction question?
for the reaction 2NOBr(g)----->2NO(g) +Br2(g), the rate of equation is -d[NOBr]/dt =k[NOBr]^2. the overall rate reaction =

When you are given a rate equation, you can easily tell the overall order of reaction.
lets the rate equation be
rate = k [X] [Y]^2 [Z]^3
We can conclude that:
1) The order of reaction with respect to (wrt) X is 1( because the equation shows that the concentration of X is raised to power 1)
2) The order of reaction wrt Y is 2.
3) The order of reaction wrt Z is 3
4) The overall order of reaction is 1 + 2 + 3 = 6
So, the answer to your question is 2.
