The increase in rate constant of a chemical reaction with increasing temperature is due to the fact$(s)$ that:
- Athe number of collisions among the reactant molecules increases with increasing temperature
- Bthe activation energy of the reaction decreases with increasing temperature
- Cthe concentration of the reactant molecules increases with increasing temperature
- Dthe number of reactant molecules acquiring the activation energy increases with increasing temperature
