Consider the reaction 2 ~A +2 ~B C +2 D . If the concentration of A is doubled at constant B , the rate increases by a factor 4 . If the concentration of B is doubled at constant A , rate is doubled. What is the rate law?
Options
- Ar=k[A]²[B]²
- Br=k[A]⁴[B]²
- Cr=k[A][B]²
- Dr=k[A]²[B]
Correct answer
D. r=k[A]²[B]
Step-by-step solution
A + B ₂ AB + B Given Rate [ A ] and not on [ B ] Rate depends on concentration of reactants. Rate = k [ A ]
