What equation is used to calculate the free energy change of a reaction?
Delta G (written triangle G) = Delta H -T Delta S
What does a delta symbol mean in a reaction?
The delta symbol in a chemical equation stands for "change". Since you have to break and reform the bonds between atoms in molecules to have a chemical reaction there is going to be a change, whether it be in the thermal energy, chemical energy, phase of the matter etc.
A chemical reaction that has a positive ΔG is correctly described as?
This is a nonspontaneous reaction, which means that it is reactant-favored. According to the second law of thermodynamics, product-favored reactions must have a negative delta G.It can also be described as an endergonic reaction - that is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
What statement correctly describes an endothermic chemical reaction?
higher potential energy and delta h increases
What information does Gibbs free energy give about a reaction?
It tells if the reaction will process spontaneously or not
When a chemical reaction has a negative delta G is the reaction exothermic or endothermic?
When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative. Hope this helps :)
What is true when two reactants combine in an exothermic reaction?
Exothermic Reactions: The delta h is always NEGATIVE! Energy is released (delta is the little triangle in front of the H)
What equation is used to calculate the free energy change of a reaction?
Delta G (written triangle G) = Delta H -T Delta S
What equation is used to calculate the free energy change a reaction?
Delta G (written triangle G) = Delta H -T Delta S
During the course of which type of reaction is energy consumed?
Any reaction that consumes energy, or has a positive delta(H), is called an endothermic 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)

higher potential energy and delta h increases
What information does gibb's free energy give about reaction?
When the Gibbs free energy for a reaction is greater than zero, the reaction is "disfavored" - won't proceed in that direction - in fact it may try go in the reverse direction if possible. When the Gibbs free energy for a reaction is less than zero, the reaction is "favored" - it should proceed as written spontaneously. When the Gibbs free energy for a reaction is exactly zero - it is in equilibrium, with the forward and back ward reactions occurring at the same rate.
What information does Gibbs free energy give about a reaction?
It tells if the reaction will process spontaneously or not
What does the delta h of a reaction represent?
Either the change (which the delta refers to) of the height (which the h represents).
