This reaction progress diagram shows the changes during a 3-step chemical reaction and the effects on energy. In each step of the reaction, how does the energy change from reactants to products?

Question

Question 9 options:

energy is halved

energy is tripled

energy is absorbed

energy is released

Answer 1

The answer cannot be determined without seeing the actual reaction progress diagram. It is important to look at the direction of the arrows and the relative positions of the reactants and products on the diagram to determine how the energy changes in each step of the reaction.
