Which equation is used to describe reaction rates?


S products−S reactants



∆H−T∆S



pV=nRT



∆(reactant or product)/∆time

Answer 1

Answer: $Rate=\frac{\Delta_{\text {reactants or products}}}{\Delta_{time}}$

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

Rate of reaction can be defined in terms of reactants or products. It is the ratio of disappearance of reactants per unit time or ratio of appearance of products per unit time.

$Rate=\frac{\Delta_{reactants}}{\Delta_{time}}$ or $Rate=\frac{\Delta_{products}}{\Delta_{time}}$

$S_{products}-S_{reactants}$ gives the entropy change for the reaction.

$\Delta H-T\Delta S$ gives Gibbs free energy.

$PV=nRT$ is the ideal gas equation.
