Estimate the temperature where Delta G = 0 for the following reaction (Given: Delta H=-176 and Delta S = -284.5 J/K
NH3 + HCl --> NH4Cl
dG = dH - TdS
You know dG = 0, dH, and dS, solve for T (in kelvin).
I note you don't have any units for dH but I assume that is -176 kJ/mol. If that is so you will need to convert dS to kJ/mol before you do the calculation.
