Question

The conversion of solid CO2 ("dry ice") to CO2 gas is product-favored at room temperature. What would be the signs for ΔG, ΔH, and ΔS at room temperature?

CO2(s) --> CO2(g)

ΔG = (+) ΔH = (+) ΔS = (-)

ΔG = (-) ΔH = (+) ΔS = (-)

ΔG = (+) ΔH = (+) ΔS = (+)

ΔG = (-) ΔH = (+) ΔS = (+)

ΔG = (-) ΔH = (-) ΔS = (+)

Answer 1

CO2 (s) (0219) > This dry ice is the product favoured reaction. So will be Standard gibbs fr negective AG =-ive so CO2 گر to aseous phase form solid going phase, by absoobing the heat it is So endothermic process So OH = +ive CO2 (s) -7 means Ys CO219) solid gas. phase is changing changing from from solid to ges, entropy randomness is increasing increasing our answer is AG= (-); OH = (+); Os = (+) su so OS = tive 1 So / 2 As
