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.

Consider the reaction pathway graph below.Which statement accurately describes this graph?

Question illustration
A
It represents an endothermic reaction because the products have more energy than the reactants.
B
It represents an exothermic reaction because the products have more energy than the reactants.
C
It represents an endothermic reaction because the reactants have more energy than the products.
D
It represents an exothermic reaction because the reactants have more energy than the products.
4

8

Consider the reaction pathway graph for a two-step reaction below.Which inference does the graph best support?

Question illustration
A
Step A is endothermic, so it is faster than Step B.
B
Step A has a greater activation energy, so it is faster than Step B.
C
Step A is endothermic, so it is slower than Step B.
D
Step A has a greater activation energy, so it is slower than Step B.

Question illustration
A
condensation
B
dehydration
C
decomposition
D
melting
