FREE Expert Solution

We’re being asked to calculate ΔG° at 298 K for the given reactions:


We can use the following equation to solve for ΔG˚rxn:

ΔG°rxn=ΔG°f, prod-ΔG°f, react

The values for ΔG˚f can be looked up in textbooks or online:

Note that we need to multiply each ΔG˚f by the stoichiometric coefficient since ΔG˚f is in kJ/mol.

Problem Details

Calculate ΔG° at 298 K for the following reactions.

Part A

NH3(g) + HBr(g) → NH4Br(s)

Part B

2 KClO3(s) → 2 KCl(s) + 3 O2(g)

Part C

CH4(g) + 3 Cl2(g → CHCl3(g) + 3 HCl(g)

ΔG°f for CHCl3(g) is - 70.4 kJ/mol
