Term
-q rxn=q soln=mSΔT
Definition
-q rxn- heat given off by reaction
q soln- heat given off by solution
m- mass of solution
S- specific heat (given)
ΔT- temperature change
Term
ΔH= qrxn/nLR x vLR/mol rxn
Definition
ΔH- change in enthalpy
q rxn- heat given off
nLR- moles of limiting reactant
vLR- stoich of limiting reactant
mol rxn- reaction as is written
Term
ΔH(S, G)= H final- H initial
Definition
Change in S, G, H, is final minus inital
Term
ΔS= ΔH unavailable/ Temperature
Definition
ΔH unavailable- heat given off by bonds, etc.
Temp- temp..
Term
ΔH
Definition
Enthalpy-
Term
ΔS
Definition
Entropy-
Term
ΔG= ΔH-TΔS= -RTlnK= -nFE
Definition
ΔG is Gibbs Free energy
ΔH is enthalpy
ΔS is entropy
T is Temp
R is a constant
K is the equilibrium constant
n is the number of ELECTRONS
F is a Constant
E is the voltage
Term
ΔG= ΔG+RTlnQ
Definition
ΔG and ΔG° are gibbs free energy
R is constant
T is temp
Q is the reactant quotient, ration of products/reactants.
Term
ΔG° OR S, H
Definition
The ° represents the standard state condtitions of a reaction.
Term
Erxn= E red + E ox
Definition
Energy of redox and oxidation
Term
E=E°-(RT/nF)lnQ
Definition
Just relates the E to the lnQ and such
Term
lnK= -ΔH°/RT + ΔS°/R
Definition
natural log of the equilibrium constand is equal to the negative change in enthaply over constant R and T plus the total change in entropy over Constant R
