Answer to Question #278473 in Chemistry for michelle

Question

If the rate law for a hypothetical reaction is r = k[NaOH]²[H₂]¹[SO₃]⁰, what is the overall order of reaction?

1. second
2. zero
3. third
4. first
5. fourth

Answer 1

Solution:

r = k[NaOH]²[H₂]¹[SO₃]⁰

order in NaOH = 2;

order in H₂ = 1;

order in SO₃ = 0;

Thus, the overall order of reaction = 2 + 1 + 0 = 3

Answer: 3) third
