Question

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

Answer 1

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.
