which expression represents the heat of reaction for a chemical change in terms of potential energy, pe?

Anastaziya [24]

The expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).

<h3>What is potential energy?</h3>

Potential energy is any type of energy stored to perform physical work in a given period of time.

Conversely, kinetic energy is motion (movement) energy used when performing physical work.

In conclusion, the expression (PE products) - (PE reactants) represents the heat of reaction for a chemical change in terms of PE (potential energy).
