explanation:
example : CO2 (s) ------------> CO2 (g)
here solid to gas means : S = + ve
: H = + ve
G = H - T S
for spontaneous reaction H < T S . so G will negative high temperature is needed

need it asap plz 1) Consider the following reaction: CO(g) + H2O(g) + H2(g) + CO2(B) AHP (l/mol) -110.5 -241.8 -393.5 SU/K-mol) 197.9 188.7 131.0 213.6 a. Calculate the Standard Gibbs Free Energy (AG) and determine whether the reaction is spontaneous in the forward direction at 374K. (374K was chosen because it's just above the normal boiling point of water, which is the lowest temperature where the "standard" 1atm of water vapor can exist.) b. Calculate the equilibrium constant for...
