Solution: Draw the potential energy diagram for the combustion of propane:C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) + 2219.9 kJ

Solution: Draw the potential energy diagram for the combustion of propane:C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) + 2219.9 kJ

Problem

Draw the potential energy diagram for the combustion of propane:

C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) + 2219.9 kJ

Solution

We have to draw a potential energy diagram for the given reaction:

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g) + 2219.9 kJ

This reaction is the combustion of propane (C3H8).

Combustion is a reaction where a compound burns in oxygen to produce carbon dioxide (CO2) and water (H2O).

To draw the potential energy diagram for this reaction, we have to first determine whether this reaction is endothermic or exothermic.

This is because endothermic and exothermic reactions have different potential energy diagrams.

Let’s start by analyzing the equation.
