Determine the standard free energy change for the reaction 2 H₂(g)+ O₂(g)$\to$ 2 H₂O(g),given

Question

Quizplus · Accepted Answer

The standard free energy change (ΔG°) for a reaction can be calculated using the formula:

ΔG° = ΣnΔG°f(products) - ΣnΔG°f(reactants)

Where ΔG°f is the standard molar free energy of formation for each species involved in the reaction, and n is the stoichiometric coefficient for each species.

Using the given values, we can calculate the ΔG° for the reaction as follows:

ΔG° = [2(-130.6) + (-205.0)] - [2(0) + (-241.8)]
     = -228.6 kJ/mol

Therefore, the correct answer is C: "-228.6 kJ".
