Final answer:
The relative rate expression for a chemical equation can be determined based on the coefficients of the reactants and products.
Step-by-step explanation:
The relative rate expression for a chemical equation can be determined based on the coefficients of the reactants and products. In this case, the chemical equation is aA + bB → cC + dD. The relative rate expression is given by:
Relative Rate = k[A]^a [B]^b
Where k is the rate constant, [A] and [B] are the concentrations of reactants A and B, and a and b are the stoichiometric coefficients of A and B in the balanced equation.
