  • Moles & CO2 and N2 & 3H2 reactions & Matter

    Therefore three moles would have 3*6.022*1023 = 1.8066*1024 molecules B. Considering the reaction: N2(g) + 3H2(g) → 2NH3(g) Explain why this reaction is spontaneous even though it results in matter being less dispersed.

  • Understanding Gibbs Free Energy Change

    Although a reaction may be spontaneous, it may not occur at an observable rate. The speed of a reaction involves kinetics, not thermodynamics. Gibbs free energy is not a kinetic term, it is a thermodynamic term.

  • Conversion of Diamond to Graphite

    A spontaneous reaction is one which once started will proceed without outside intervention. But the direction of the reaction depends on the magnitude and sign of the free energy change.
