A chemical engineer is analyzing a reaction in which methanol (CH3OH) is synthesized from carbon monoxide (CO) and hydrogen gas (H2). The reaction has a change in enthalpy (ΔH) of -128.0 kJ/mol and a change in entropy (ΔS) of -0.259 kJ/mol·K. The engineer wants to find out at what temperature, in Kelvin, this reaction would be spontaneous. Applying the concept of Gibbs Free Energy, can you help the engineer calculate this temperature?

520.9 K

450.3 K

600.5 K

350.7 K

494.2 K
