The rate constant for the decomposition ...

The rate constant for the decomposition of hydrocarbons is `2.418xx10^(-5)s^(-1)` at `546K`. If the energy of activation is `179.9kJ mol^(-1)`, what will be the value of pre`-`exponential factor?

AI Generated Solution

To find the pre-exponential factor (A) for the decomposition of hydrocarbons, we can use the Arrhenius equation, which is given by: \[ k = A e^{-\frac{E_a}{RT}} \] Where: - \( k \) is the rate constant, - \( A \) is the pre-exponential factor, - \( E_a \) is the energy of activation, ...
