Question

at the end of this reaction, has energy been released or absorbed? (potential energy diagram with reaction coordinate, a+b, c) options: there is not enough information to tell. released. absorbed. there is not change in the amount of energy in the system.

Explanation:

Step1: Analyze the energy diagram

In a reaction energy diagram, if the products (C) have lower potential energy than the reactants (A + B), energy is released. Here, the graph shows that the potential energy of A + B is higher than that of C.

Step2: Determine energy change

When reactants have higher energy than products, the reaction releases energy (exothermic), as the system loses energy to the surroundings.

Answer:

Released
