🤓 Based on our data, we think this question is relevant for Professor Geissler's class at CAL.
Hydrogen peroxide can be prepared in several ways. One method is the reaction between hydrogen and oxygen, another method is the reaction between water and oxygen. Calculate the ΔG°rxn (kj•mol-1 ) of each reaction below using values from this table.
(1) H2 (g) + O2 (g) ⇌ H2O2 (l)
(2) H2O (l) + 1/2 O2 (g) ⇌ H2O2 (l)
Which method requires less energy under standard conditions?
