Question

Consider the following reaction:
CaO(s) + CO2(g) → CaCO3(s); = -130.9 kJ at 298 K
At what partial pressure of CO2(g) will the reaction no longer be spontaneous at 298K? (R= 0.0821 L·atm/(K·mol) = 8.31 J/(K·mol))
A) 1.59 x108atm
B) 1.00 atm
C) 6.28 x10-9atm
D) 8.77 x1022atm
E) 1.14 x10-23atm
