Show and explain each step (neatly in complete sentences), indicate units, and specify the correct number of significant figures. A friend wants to sell you a catalyst that allows benzene to be formed by passing H2 (g) over graphite at 25 ˚C and 1 atm. Should you buy? Explain.

Solutions

Expert Solution

(a) For the reaction

6C(s) + 3H2(g) → C6H6(l) at 298 K

ΔGo = [(130)] - [0 + 0]

= +130 kJ mol-1

The + sign shows this is not a spontaneous reaction at these conditions, therefore do not buy.
