GAS MIXTURES Then Ideal gas (all fugacities equal to partial pressure) Liquids \ Ideal liquid Phase
Thus, if The reaction proceeds as written and vice versa. We now define standard state and activity as follows: That is, Then: Or (definition of equilibrium Constant)

Therefore For real gases (using Lewis and Randall ), we have that a i =y i P φ K a (T)=K y K P K φ Temperature dependence

Unformatted text preview: Now: . Then (van’t Hoff equation) Integrating assuming heat of reaction constant we get the simplified relation Leading to But is heat of reaction is a function of temperature, Then SOLIDS PRESENT We use activity of a solid=1. Thus solids do not decompose if gas products K y >K a CONVERSION Substitute x i by N i /Sum_N i using Then K a (T)=K y K P Becomes only a function of T and X (we assume K φ =1) SEVERAL REACTIONS...
