Homework Help: Chemistry

Posted by Anonymous on Saturday, March 13, 2010 at 12:47am.

Calculate the free energy (ΔG˚) of reaction (kJ) for the equation as written at 298 K (Dependence of temperature on enthalpy can be disregard). If the answer is negative, enter the sign and then the magnitude. Express your answer to three significant figures.

CaO(s) + H2O(l) → Ca(OH)2(s)

I know this part (Hess's Law stuff):
FYI the numbers were given enthalpy values.

Then you plug it in the equation and solve for DeltaG, but when they say to disregard the temperature, does that mean I don't plug in the 298 to T or do I?
