Given that the activation energy (Ea) for a reaction is 75 kJ/mol, how would the rate constant (k) change if the temperature is increased from 298 K to 313 K?
💡 Hint: Calculate values using the exponential form of the Arrhenius equation.
If a catalyst decreases the activation energy from 100 kJ/mol to 70 kJ/mol, how will this affect the rate of reaction at a constant temperature of 298 K?
💡 Hint: Focus on how lowering Ea influences k.
