Question

Given the following equation,

H2O(g) + CO(g) → H2(g) + CO2(g) ΔG°rxn = -28.6 kJ
Calculate ΔG°rxn for the following reaction.

Answer 1

To calculate the ΔG°rxn, we can use Hess's law and the given data to write two equations that can be added together to give the desired equation. By reversing the combustion of the CO equation and multiplying it by 2, we can obtain 2 mol of CO as the reactant.

Step-by-step explanation:

The question asks to calculate the ΔG°rxn for a given reaction. To solve this problem using Hess's law and the given data, we can write two equations that can be added together to give the desired equation and for which the enthalpy changes are known. By reversing the combustion of the CO equation and multiplying it by 2, we can obtain 2 mol of CO as the reactant.
