Question

two reactions gave potential energy graphs with some overlap. point \d\ matched reaction 1. what can be said about the reactions? 1) h + e --> f 2) g + k --> m potential energy graph 1) is endothermic and 2) is exothermic 1) absorbs energy and 2) is releases 1) has poasitive energy and 2) has negative energy 1) releases energy and 2) absorbs energy

Explanation:

Step1: Analyze endothermic and exothermic reactions

In an exothermic reaction, the products have lower energy than the reactants (energy is released). In an endothermic reaction, the products have higher energy than the reactants (energy is absorbed).

Step2: Determine reaction type for reaction 1

Since point "d" (products of reaction 1: \(F\)) has lower energy than the reactants (\(H + E\)) (assuming \(a\) is reactants for reaction 1), reaction 1 (\(H+E
ightarrow F\)) is exothermic (releases energy).

Step3: Determine reaction type for reaction 2

Assuming \(a\) is not reactants for reaction 2 (as \(d\) is for reaction 1), and if we consider the other part of the graph (say if \(c\) is products for reaction 2: \(M\) and assume reactants (\(G + K\)) have lower energy than \(M\)), reaction 2 (\(G + K
ightarrow M\)) is endothermic (absorbs energy)

Answer:

1. releases energy and 2) absorbs energy
