Calculate the activation energy of a reaction whose reaction rate at `300 K` double for `10 K` rise in temperature.

Text Solution

AI Generated Solution

To calculate the activation energy of a reaction whose rate doubles when the temperature increases from 300 K to 310 K, we can use the Arrhenius equation. Here’s the step-by-step solution: ### Step 1: Understand the relationship between rate constants and temperature The problem states that the reaction rate doubles when the temperature increases by 10 K. This can be expressed mathematically as: \[ \frac{R_2}{R_1} = \frac{K_2}{K_1} = 2 \] where \( R_1 \) and \( R_2 \) are the reaction rates at temperatures \( T_1 \) and \( T_2 \) respectively. ...

Calculate the activation energy of a reaction whose reaction rate at 310 K gets doubled for 10 K rise in temperature.

The activation energy of a reaction is zero. The rate constant of this reaction

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If the rate of reaction doubles for 10^(@)C rise of temperature form 290K to 300K, the activation energy of the reaction will be approximately :

The activation energy of a reaction is zero. Will the rate constant of the reaction depend upon temperature ?

The rate of a reaction quadruples when the temperature changes from 293K to 313K . Calculate the energy of activation of the reaction assuming that it does not change with temperature.

The rate of a reaction increases four times when the temperature changes from 300 K to 320 K. Calculate the energy of activation of the reaction, assuming that it does not change with temperature. (R = 8.314 JK^(-1) mol^(-1) )
