Calculate the standard free energy for the reaction given. 2 CH₃OH(l)+ 3 O₂(g)→ 2 CO₂(g)+ 4 H₂O(l)

Question

Quizplus · Accepted Answer

To calculate the standard free energy for the given reaction, we need to use the equation:

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

where ΔG°f is the standard free energy of formation for each species.

Using standard free energy of formation values from a table, we get:

ΔG° = [2(-394.36) + 4(0) + 3(-205.1)] - [2(-250.12) + 2(-285.83)]
ΔG° = -1404.8 kJ

Therefore, the best choice is C, with an explanation as shown above.
