28. Solving a chemistry problem

20. In a chemical reactor of infinitely large dimensions, interaction between gaseous substances takes place. Substances 1 and 2 are initial, and 3 and 4 are products. The partial pressures of the participants in the reactions, the temperature, and the standard changes in the Gibbs energy of the reactions are shown in the table. Calculate the change in the Gibbs energy during one run of the reaction (ξ = 1) under the given conditions. What can be said about the possibility of a reaction?
