The gibbs energy for the decomposition
WebExergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called … WebThermal decomposition of gaseous X2 to gaseous X at 298 K takes place according to the following equation: X2(g) ⇌2X(g) The standard reaction Gibbs energy, ΔrG0, of this reaction is positive. At the start of the reaction, there is one mole of X2 and no X. As the reaction proceeds, the number of moles of X formed is given by β.
