Answer:
Explanation:
a) Here, we want to get the class of the reaction
An endothermic reaction absorbs energy from the surroundings and as such, the change in enthalpy value is positive
This can be deduced from the position of energy in the chemical equation. Since it is added to the reactant side, it is for an endothermic reaction
b) Here, we want to draw a potential energy diagram for the reaction
We have this as follows:
