Gibbs free energy of ca oh 2

WebThe standard Gibbs energy of the reaction K2CrO4(aq) + 2 Ag(s) + 2 FeCl3(aq) → Ag2CrO4(s) + 2 FeCl2(aq) + 2 KCl(aq) is −62.5 kJ mol−1 at 298 K. (a) Calculate the standard potential of the corresponding galvanic cell and (b) the standard potential of the Ag2CrO4/Ag,CrO42− couple. WebThis right here is in joules. So if we want to write everything in kilojoules, since we already wrote that down, let's write this in kilojoules. So it's 0.242 kilojoules per Kelvin. And so now our Gibbs free energy right here is going to be minus 890 kilojoules minus 290-- so the minus and the minus, you get a plus.

WebΔ H is the enthalpy change of the system. Multiplying both sides of this equation by − T, and rearranging yields the following: − TΔSuniv = ΔH − TΔS. Comparing this equation to the previous one for free energy change shows the following relation: ΔG = − TΔSuniv. The free energy change is therefore a reliable indicator of the ...
