Please help:Determine the overall orders of the reactions to which the following rate laws apply.?
(a) Rate = k[NO2]2
(b) Rate = k
(c) Rate = k[H2][Br2]1/2
(d) Rate = k[NO]2[O2]

Determining the overall order is done simply by adding up the exponents of the concentrations.
(a) Second order
**It only has [NO2] squared, so it's second
(b) Zero order
**This rate law has no concentration component, so there are zero exponents
(c) 1.5 order
**The exponent of [H2] is 1 and the exponent of [Br2] is 0.5. So added together, it is 1.5
(d) Third order
**The exponent of [NO] is 2 and the exponent of [O2] is 1. So added together, it is 3.
