kc, or the rate constant, does not change because it is a characteristic of a specific reaction at a given temperature. It is determined by the nature of the reaction and the specific reactants involved. Once the reaction conditions are set, such as temperature and pressure, the rate constant remains constant for that specific reaction. Therefore, as long as the reaction conditions remain the same, kc does not change. **

Yes, generally speaking, 4-cylinder engines are more fuel-efficient than larger engines with more cylinders. This is because 4-cylinder engines are smaller and lighter, requiring less fuel to operate.
