A. ΔG, ΔH and ΔS are positive
B. ΔG, ΔH and ΔS are negative
C. ΔG, ΔH are negative and ΔS is positive
D. ΔG is negative and ΔH, ΔS are positive
Answer: Option B
Standard entropy of crystalline carbon monoxide (in kJ/mol) at 0 K is around
A. 0.03
B. 2.50
C. zero
D. 5.76
A. nR In(Vf/Vi)
B. zero
C. less than zero
D. greater than zero
A. -12.74 J/K/mol
B. -6.37 J/K/mol
C. 6.37 J/K/mol
D. 12.74 J/K/mol
A. ΔS° = -37.65 J/K/mol; negative sign indicates that there is a decrease in the gaseous species during the reaction
B. ΔS° = -198.7 J/K/mol; negative sign indicates that there is a decrease in the gaseous species during the reaction
C. ΔS° = -31.25 J/K/mol; negative sign indicates that there is a decrease in the gaseous species during the reaction
D. ΔS° = +31.25 J/K/mol; positive sign indicates that the reaction is spontaneous
