ystem The relationships between ÎHsstem and ÎSsurroundings at constant temperature (ASsurroundings- thermodynamics in more useful quantities allow us to rewrite and rearrange the 2nd law of for ÎSun) (substitute-T (multiply through by-T and rearrange) -TAS,ni = Î ,ya-TASay8 Given that the Gibbs Free Energy Change, AG, is We obtain the very important and useful equation that allows us to predict spontaneity sys Commonly written as: ÎG-Î 1-TAS When starting with Standard State Conditions: Î no-Î r-TASã Part C Click and drag the correct answers Refer to the Second Law of Thermodynamics Temperature, T is alwavs measured in Kelvin, what is the sign of T? What is the sign of ASun for a spontaneous process? What is the sign of ASuniv for a nonspontaneous process? What is the value of ASuny for a system at equilibrium? positive negative zero Consider the signs of T and ASuniv (from above) and the equation: ÎG =-TASuniv it depends what sign for ÎG indicates a spontaneous reaction? what sign for ÎG indicates a nonspontaneous reaction? what value of ÎG indicates a system at equilibrium?
