enthalpy change^H is +23kJ mol-1 of phosphine (PH3) for the reaction
a) Calc. entropy change for this reaction. Explain how this information allows you to determine the spontaneity or non-spontaneity of this reaction at any temp (S for PH3 is 210JK-1 mol-1)
b) do these results indicate anything about the possibility of the existence of phosphine? explain your answer.
