Equilibrium expression
« on: July 19, 2012, 05:41:35 AM »
The reaction aA+bB :rarrow: cC+dD has equilibrium expression

K=C^cD^d/A^aB^b

However, the reaction 2aA+2bB :rarrow: 2cC+2dD has equilibrium expression

K=C^(2c)D^(2d)/A^(2a)B^(2b)

But both these reactions are the same. So, how can it have 2 equilibrium expressions?

From stoichiometric point of view these reaction are different but their equlibrium constants are related K and K2 (the same K)
