Question

What is meant by relative rates of reaction?

Answer 1

Dear Student,

Relative rate of reaction means that reactants and products disappaear or appear at rates proportional to their coefficients in the balanced chemical equation.
$$\begin{gathered} \mathrm{aA}+\mathrm{bB}\to \mathrm{cC}+\mathrm{dD} \\ \mathrm{Relative}\mathrm{rates}\mathrm{can}\mathrm{be}\mathrm{calculated}\mathrm{as}: \\ \mathrm{Rate}=-\frac{1}{\mathrm{a}}\frac{∆\left[\mathrm{A}\right]}{∆\mathrm{t}}=-\frac{1}{\mathrm{b}}\frac{∆\left[\mathrm{B}\right]}{∆\mathrm{t}}=\frac{1}{\mathrm{c}}\frac{∆\left[\mathrm{C}\right]}{∆\mathrm{t}}=\frac{1}{\mathrm{d}}\frac{∆\left[\mathrm{D}\right]}{∆\mathrm{t}} \end{gathered}$$
