... (There is an interesting problem in going from Equation 5a to Equation 5b which is not usually discussed. In Equation 5a the coefficients of the balanced chemical equation, a, b, etc. have units of moles, so that, for example, cC is moles times Joules per mole which leaves just units of Joules. How ...

THERMODYNAMICS
... Many forms of energy can be interconverted and that in chemical processes, chemical energy is converted to heat energy or vice versa. The amount of heat a process uses (endothermic) or gives off (exothermic) can tell us a great deal about that process. For this reason it is important for us to be ...

What is Thermodynamics?
... changes as a function of T and P. • Regardless of T and P, a reaction occurs spontaneously in the direction that will reduce the value of ∆GR because ∆GR is the driving energy for the chemical reaction. • For any T and P conditions, a reaction at equilibrium has ∆GR = 0 because when a reaction is at ...

P2-Equilibrium Activity
... Not all chemical reactions reach completion where the limiting reactant is consumed completely. In fact, most chemical reactions that occur in living systems never reach completion. Rather, they produce some amount of product then appear to stop reacting in the forward direction, never fully consumi ...
