The effect of temperature on the rate of a reaction is given by:
Correct answer: C. Arrhenius equation
- A. Henderson's equation
- B. General gas equation
- C. Arrhenius equation
- D. Van der Waals equation
Explanation
In physical chemistry, the 'Arrhenius equation' is a formula for the temperature dependence of reaction rates- k= Ae(-Ea/RT) where A= Arrhenius constant, Ea= activation energy, R= universal gas constant, T= absolute temperature. So, C stands correct. 'Henderson's equation' is used to calculate the pH of the buffer solution, not the effect of temperature on reaction rates. The general gas equation and Van Der Waals equation are both used to study the changes in the volume of ideal gases at different pressures and temperatures. Both of these equations have nothing to do with reaction rates.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
