a potential energy diagram is shown. what is the total change in enthalpy of this reaction? 25 kj 30 kj 35 kj 55 kj
Answer
Explanation:
Step1: Recall enthalpy - change formula
$\Delta H=H_{products}-H_{reactants}$
Step2: Identify product and reactant enthalpies
From the graph, $H_{products} = 55\ kJ$ and $H_{reactants}=30\ kJ$
Step3: Calculate the enthalpy change
$\Delta H=55 - 30=25\ kJ$
Answer:
25 kJ
