Question

Write down a general expression for Endothermic & exothermic reaction representing heat​

Answer 1

Explanation:

For exothermic,

The general equation for an exothermic reaction is: Reactants → Products + Energy. Note: ΔH represents the change in energy. If the energy produced in an exothermic reaction is released as heat, it results in a rise in temperature.

For endothermic,

We saw that in exothermic reactions, heat is given out. Whereas in endothermic reactions, heat is taken in. We also saw that to represent exothermic reaction, we write plus heat or delta on the product side. Whereas to represent endothermic reactions, we write heat or energy on top of the arrow.

Hope it helps to you.......

Answer 2

Answer:

Reactants + Energy → Products

Reactants → Products + Energy.
