In a given chemical reaction, the energy of the products is less than the energy of the reactants. which statement is true for this chemical reaction?

a. energy is absorbed in the reaction.
b. energy is released in the reaction.
c. there is no transfer of energy in the reaction.
d. energy is lost in the reaction.

The correct answer is Option B.

Explanation:

Enthalpy change of reaction is defined as the difference in the potential energy of the products and the potential energy of the reactants. It is represented as

The equation used to represent enthalpy change of the reaction follows:

As, energy of products is less than the energy of reactants, so the enthalpy change of the reaction comes out to be negative.

Thus, the correct answer is Option B.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
