Created by StemPy LabAssertion (A): The rate of a reaction may double for a rise of . Reason (R): The number of molecules with energy above the activation energy rises sharply with temperature.
← All Quizzes
← Statement I: In the collision theory, every collision that has more than the threshold energy leads to a reaction. Statement II: The molecules must also meet in the right orientation. Choose the correct option.Statements about a catalyst: 1. It lowers the activation energy of the forward and of the reverse reaction. 2. It changes the enthalpy change of the reaction. 3. It does not change the equilibrium constant. 4. It can start a reaction that has a positive Δ G. How many of these are correct? →
