Given the equation I2 (s) + 62.4kJ - - > I2 (g), which of the following is true:

A) The reaction is exothermic

B) H = + 62.4kJ

C) H = - 62.4kJ

D) The reaction releases heat

The statements that are true are that;

The reaction is exothermic;

H = - 62.4 kJ

And also the reaction releases energy.

Exothermic reactions are chemical reactions that release energy to the environment to the environment causing the reaction mixture and the surroundings become more hotter; therefore the delta H is negative since the heat of the products is less that that of the reactants.
