Question

Which statement best describes how to read a reaction pathway graph for an endothermic reaction?

A) Reactants absorb a minimum amount of energy and then release a larger amount of energy as products form.
B) Reactants release a minimum amount of energy and then absorb a larger amount of energy as products form.
C) Reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.
D) Reactants release a minimum amount of energy and then absorb a smaller amount of energy as products form.

Answer 1

C) Reactants absorb a minimum amount of energy and then release a smaller

amount of energy as products form.

Step-by-step explanation:

The statement that best describes how to read a reaction pathway from the graph of an endothermic reaction is that, reactants absorb a minimum amount of energy and then release a smaller amount of energy as products form.

In an endothermic change, heat is absorbed from the surrounding.

• As such, the surrounding becomes colder at the end of the reaction.
• On a graph of an endothermic reaction, the reactants absorbs a minimum energy.
• As the reaction proceeds, the products gives off an even lesser amount of energy.
