Question:medium

What is the effect of temperature on the rate constant of a reaction? 

Show Hint

An increase in temperature results in an increase in the rate constant, accelerating the reaction.

Solution and Explanation

Reaction rate constants typically rise with temperature, as described by the Arrhenius equation. This equation indicates that the rate constant \(k\) grows exponentially with temperature. Elevated temperatures result in a greater number of molecules possessing sufficient energy to surpass the activation energy barrier, thereby increasing the rate constant. \[ k = A \cdot e^{-\frac{E_a}{RT}} \] Here: - \(k\) denotes the rate constant, - \(A\) is the frequency factor, - \(E_a\) represents the activation energy, - \(R\) is the gas constant, - \(T\) signifies the temperature in Kelvin.
