Question

Explain velocity (rate) constant of a reaction.

Hint:

The rate constant increases with temperature, as explained by the Arrhenius equation.

Answer 1

The velocity (rate) constant \( k \) of a reaction is the proportionality factor in the rate equation: \[ \text{Rate} = k[A]^m[B]^n, \] where \( m \) and \( n \) are the orders of the reaction. \( k \) depends on temperature and the nature of the reactants.
