    Calculate the standard reaction enthalpy, entropy and free energy at 298K for the following reactions:
    a) CH3OH(l) + O2 (g) → CO2 (g) + H2O(l)
    b) P(s,white) + O2 (g) → P4O10 (s)
    c) sucrose + H2O (l) → α glucose + β fructose

    Solution:
    The standard enthalpy of reaction (H0reaction) can be solved from the standard enthalpy of formation (H0f) of reactants and products following the equation:
    H0reaction = nH0f of products - nH0f of reactants
    Where n and m are coefficients of products and reactants respectively in the balanced equation
    The standard enthalpy of formation (H0f) values are found in literatures.
    Note:
    H0f of an element in its standard state is zero.

    Similarly, the standard entropy of reaction (S0reaction) can be solved from the standard molar entropy (S0) of reactants and products following the equation:
    S0reaction = nS0 of products - nS0 of reactants

    Hence,
    1. 2CH3OH(l) + 3O2 (g) ...
