Question

The rate of a reaction is expressed as: $+\frac{1}{2}\frac{\Delta[C]}{\Delta t} = \frac{1}{3}\frac{\Delta[D]}{\Delta t} = \frac{1}{4}\left(-\frac{\Delta[A]}{\Delta t}\right) = -\frac{\Delta[B]}{\Delta t}$. The corresponding balanced chemical equation is:

Prashant Kotian · Accepted Answer

Correct answer: A. From the rate expression, reactants are and (negative sign) and products are and (positive sign). The stoichiometric coefficients are the denominators in the rate expression. Thus, the reaction is .
