True or false. If false, explain why.

a. The relation G = H – T S is valid for all processes.

b. G = A + pV.

c. G is undefined for a process in which T changes.

d. G = 0 for a reversible phase change at constant T and p.

e. G = 0 for a chemical reaction in equilibroum at constant T and p.

f. sysS  surrS is positive for every irreversible process.

g. fH298 is zero for O2.h. fH400 is zero for O2.

i. For the combustion of glucose, cST = cHT / T at 298 K.

j. When an exothermic reaction in a closed system with only P-V work is run under isobaric and adiabatic conditions, rH = 0.

k. When an exothermic reaction in a closed system with only P-V work is run under isobaric and isothermal conditions, rH = 0.
