    The Gibbs free energy change for conversion of compound X to Compound ...
    X→Y ; ΔG = 20 kJ mol-1 ... (1)
    ATP →ADP + pi; ΔG = —30 kJ mot-1 ... (2)
    Add reaction (1) and (2)
    X + ATP → Y + ADP + p1  ΔG = 20 — 30 = —10 kJ mol-1 
    In order to calculate the net Gibbs energy of a reaction, if the Gibbs energy of two separate reactions are given, add or substract the two given reactions in such a way that you obtain the desired reaction. In the same way energies are also added or subtracted.

    The Gibbs free energy change for conversion of compound X to Compound ...
    The Gibbs free energy change for the conversion of compound X to compound Y is 20 kJ mol. This indicates that the reaction is thermodynamically favorable, as the Gibbs free energy change is positive. This means that the reaction will proceed spontaneously in the forward direction, from compound X to compound Y.

    The Gibbs free energy change (ΔG) is a measure of the maximum work that can be obtained from a chemical reaction at constant temperature and pressure. A positive ΔG indicates that the reaction is non-spontaneous and requires energy input to proceed. Conversely, a negative ΔG indicates that the reaction is spontaneous and releases energy.

    In this case, the positive value of 20 kJ mol for ΔG indicates that the conversion of compound X to compound Y is non-spontaneous and requires an input of energy.
