The equilibrium constant of the WGSR is a function of temperature, and can be obtained thermodynamically from the following formula [44], (3)KP=expΔS0R-ΔH0RTPatm∑j=1Nvj''-vj' where ΔS0, ΔH0, R, T, Patm, N, and vj represent the change of total entropy on the standard ...
chemical science,chemistry- the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions constant- a number representing a quantity assumed to have a fixed value in a specified mathematical context; "the velocity of light is...
At given temperature, to find Ka: 1400K,Ka= ? 10-4 (2). Given pCO/pCO2, determine T (from which the reduction can happen.) pCO/pCO2=109/1, T=? 550K q 5.7 Variation of Equilibrium Constant with Temperature 5.7 Variation of Gibbs free energy with Temperature G ? H ? TS ? U ?
There are many different types of equilibrium constants. Some of these are binding constants, association constants, dissociation constants, stability constants, and formation constants, etc. The factors which may affect the equilibrium constant include temperature, ionic strength, and choice of solvent. ...

Besides changing the temperature, there is no way to alter the equilibrium constant. For example, adding more product or reactant will not change K. If K > 1, then the equilibrium state is product-heavy (when a fraction is more than 1, its numerator is greater than its denominator). ...
The equilibrium constant is dependent on temperature. A change in temperature can shift the equilibrium towards products or reactants, resulting in a change in the equilibrium constant. In general, an increase in temperature favors the endothermic reaction, while a decrease in temperature favors the...
The concentrations of solids, pure liquids, and solvents are not included in heterogeneous equilibrium because they do not vary significantly with temperature and are therefore treated as unity or 1. This is important to remember when formulating the equilibrium constant for a heterogeneous equilibrium ...
