Use data in the Appendix of our text, and that given below, to answer the following:(a)A friend wants to sell you a catalyst that allows benzene to be formed by passing H2 gas over carbon graphite at 298K and 1 bar pressure. Should you buy? Why? (b)Is the reaction to form solid alanine, CH3CHNH2COOH and liquid water from CH4(g), NH3(g) , and O2(g) spontaneous at 298K and P=1bar? For alanine at T=298K, use: D f Hʅ = –562.7kJ/mol, Sʅ = 129.20 J/mol, Df Gʅ = –370.24kJ/mol
