← All Quizzes
← 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?At 298 K, a reaction is run with a new catalyst. The catalysed path has a barrier 17 kJ/mol below the old one, and A is unchanged. The reaction becomes faster by what factor? →
