Answer: Option A.
∆H is less than (more negative)∆ E of the system
Explanation:
From the question, a solid yield a mixture of gases in an exothermic reaction. Exothermic reaction is a process that give out energy after the reaction, it is mostly represented by negative H, that is enthalpy .
The enthalpy is negative( ∆H) when the reaction release energy meaning that the energy that must be absorbed to break the bonds of the reactants is greater than than energy released when new bonds are formed.
From the reaction more heat is released.
