21. Calculate ΔG298 for the conversion of white phosphorus to red, if ΔH298 of red P = -17.45 kJ/mol, ΔH298 of white P=0 are known; ΔS298 red P=44.35 J/mol*K, ΔS298 white P=22.85 J/mol*K. Draw a conclusion from the result. Determine the temperature at which the transformation under consideration is possible, assuming that ΔH0T and ΔS0T are the same as at 298 K.
