Consider the following reaction of carbon monoxide with oxygen to produce carbon dioxide.
2 CO( g ) + O2( g ) → 2 CO2( g )
At what temperature will this reaction be spontaneous according to Gibbs free energy?
Δ H in kJ\moles for CO( g ) is − 110.5 and for CO 2 ( g ) is − 393.5. Δ S in J\moles K for CO( g ) is 197.6, and for CO 2 ( g ) is 213.6, O 2 ( g ) = 205.0.
A) At temperatures above − 63.1 K
B) At temperatures below 179.5 K
C) At temperatures above 415.8 K
D) At temperatures below 3272 K
