The potential energy diagram is a common way of depicting the reaction profile. The following are true about the diagram;
- The activation energy of the reaction is 35kJ.
- The enthalpy change of this reaction is 25kJ.
- The slope of the diagram is positive.
- The reaction is endothermic.
What is a potential energy diagram?
A potential energy diagram is a diagram that shows the conversion of reactants to products. It can tell us whether the reaction is endothermic or exothermic.
1) From the diagram, the activation energy of the reaction = 65 kJ - 30 kJ = 35 kJ
2) The enthalpy change of this reaction = 55kJ - 30 kJ = 25kJ.
3) The slope of the diagram is positive.
4) The reaction is endothermic.
