Compounds A and B react to form compounds C and D according to the equation: aA + bB → cC + dD. If the reaction involves intermediates and several steps, the rate law is determined by . A.) measuring the rate of the reaction for different concentrations of A and B

B.) using the coefficients of the reactants as exponents in the rate law expression

C.) measuring the changes in enthalpy and entropy at specific temperatures

D.) adding the coefficients of the reactants (their sum is the specific rate constant)
