What is delta Gº for the following reaction at 25 °C? CO(g) + 2 H2(g) = CH OH(9)
Ky = 2.1 x 10-4

21 kJ/mol

Explanation:

Step 1: Given and required data

Step 2: Write the balanced equation at equilibrium

CO(g) + 2 H₂(g) ⇄ CH₃OH(g)

Step 3: Calculate the standard Gibbs free energy of the reaction (ΔG°)

We will use the following expression.

ΔG° = - R × T × ln Kc

ΔG° = - (8.314 J/K.mol) × 298 K × ln 2.1 × 10⁻⁴ = 2.1 × 10⁴ J/mol = 21 kJ/mol

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
