Consider the hypothetical equation aA + bB → cC + dD: Which of the following represents correct rate equation?

Rate = k[A]^a

Rate = k[B]^2

Rate = k[A][B]

Rate = k[A]^a[B]^b

Explanation

The correct rate equation for the hypothetical reaction aA + bB → cC + dD is Rate = k[A]^a[B]^b.

This equation indicates that the rate of reaction depends on the concentrations of reactants A and B raised to the power of their respective stoichiometric coefficients.
