Question

Rate of reaction depends upon

• A. temperature
• B. catalyst
• C. concentration
• D. All of these

Answer 1

Answer: (D)

Rate of reaction depends upon nature of reactants, concentration of the reactants, temperature and presence of catalyst.

It concentration of reactant ↑ Rate of reaction ↑

Catalyst increases or decreases the rate of reaction

If $\Delta \text{H}=+\text{v}\text{e}$ as temperature increase rate of reaction increases

$∆H=-\text{v}\text{e}$ as temperature decreases the rate of reaction increases.
