Formic acid is the simplest carboxylic acid and can be synthesized by the oxidation of formaldehyde:
2 HCHO(g) + O2(g) → 2 HCOOH(l)
What is the value of ΔG for this reaction at 300 K under the following conditions (ΔG° = −518 kJ/mol)? Assume V = 1.00 L.
i) 0.451 mol HCHO, 0.852 mol O2, and 0.150 mol HCOOH
ii) 0.350 mol HCHO, 1.454 mol O2, and 0.950 mol HCOOH
Is the reaction spontaneous under any of these conditions?
