Notes on 11.37

Postby Emily Mei 1B » Sun Dec 03, 2017 4:23 pm

In question 11.37, eq.3 = 1/2eq1, and the K of eq.3 = (K of eq.1)^1/2. Eq.4 = 2eq.1, and K of eq. 4 = (K of eq. 1)^2. Is this pattern actually a rule?

It is a rule. When the coefficients in an chemical equation is multiplied by 2, the k is squared. This is a rule when manipulating equilibrium constants.

Are there other rules/tips/tricks that are useful for manipulating equilibrium constants?

The rule in general is for a given equation, you raise K to the power of whatever value you multiplied the chemical reaction by.

So if you multiply the equation by 3, the new value of K would be the initial K3
