Answer 1

Answer #1

cem 15 Part A Predict the conditions (high temperature, low temperature, all temperatures, or no temperatures) under which ea

explanation:

example : CO2 (s) ------------> CO2 (g)

here solid to gas means : $\Delta$ S = + ve

: $\Delta$ H = + ve

$\Delta$ G = $\Delta$ H - T $\Delta$ S

for spontaneous reaction $\Delta$ H < T $\Delta$ S . so $\Delta$ G will negative high temperature is needed
