Use the thermodynamic table to solve AS",00 for 2C0(g) + O,(g) → 2CO,(g).
(a) First perform the calculation using the following temperature-dependent heat capacities for the gases:
C®"(0,, g) = 25.67 + 0.01330T – (3.764×10*)T² – (7.310×10'")T³
C'"(CÓ, g) = 28.74 – 0.00179T + (1.046×10*)T² – (4.288×10")T³
C®"(CO,, g) = 21.64 + 0.06358T – (4.057×10*)T² + (9.700×10*)T
All heat capacities are in units of J/(mol K).
AS.
Type your answer here
J/(mol K)
