Question

are most chemical reactions exothermic or endothermic?​

Answer 1

heat release in reaction called exothermic

heat absorbed called endothermic

Answer 2

$\bigstar\huge\bf\underline{\underline{Answer:-}}$

The most chemical reactions are exothermic because:

• If more energy is released than consumed, then the chemical reaction evolves heat and is said to be exothermic.

• On the other hand if the reaction consumes more energy than it releases then the reaction absorbs heat and is said to be endothermic.

• So, most reactions are exothermic reactions.
