Calculate ΔG ° for the following reactions at 25 ° C: a) 2Mg (s) + O2 (g) → 2MgO (s); b) 2SO2 (g) + O2 (g) → 2SO3 (g); c) 2C2H6 (g) + 7O2 (g) → 4CO2 (g) + 6H2O (l)

For the reaction c6h14(g) & longrightarrow; c6h6(g) + 4h2(g), δp(h2)/δt was found to be 2.5 x 10-2 atm/s, where δp(h2) is the change in pressure of hydrogen. determine δp(c6h14)/δt for this reaction at the same time.
