Question

Does this graph show an endothermic of exothermic reaction?

Answer 1

The correct answer is option 3rd

Answer 2

Answer:

3. exothermic, because the products are at a lower energy state in the reactants

Explanation:

It is also because the average enthalpy is negative.

${ \boxed{ \triangle H = \triangle products - \triangle reactants}}$

since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
