What equation is used to calculate the free energy change of a reaction?
Delta G (written triangle G) = Delta H -T Delta S
What could make delta G become negative at a given enthalpy and entropy?
The equation for ∆G is ∆G = ∆H - T∆S H is enthalpy and S is entropySo, ∆G is negative if T∆S is greater than ∆H
What is S in the equation delta G equals delta H minus TdeltaS?
The change in enthalpy between products and reactants in a reaction
What affects the magnitude of delta G?
Delta G is the change in Gibbs free energy. Gibbs Free energy is defined as:- G= H-TS at constant temperature so the factors ar the change in enthalpy (H) and entropy (S)
What is the value of delta G at 500 K if delta H 27 kJmol and delta S 0.09 kJ(mol K)?
∆G = ∆H - T∆S∆G = 27 kJ/mole - (500 deg)(0.09 kJ/mol-deg) ∆G = 27 kJ/mole - 45 kJ/mole ∆G = - 18 kJ/mole (Note the minus sign indicating the process is spontaneous)
What is delta S in the equation delta G delta H - T delta S?

Thermodynamic properties for a chemical reaction in which amino acids are linked to form a protein?
+delta H, -delta S, +delta G
What is S in the equation delta G equals delta H minus TdeltaS?
The change in enthalpy between products and reactants in a reaction
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
What affects the magnitude of delta G?
Delta G is the change in Gibbs free energy. Gibbs Free energy is defined as:- G= H-TS at constant temperature so the factors ar the change in enthalpy (H) and entropy (S)
What is h in equation g h -t s?
The change in entropy between products and reactants in a reaction.
