Calculations Involving Equilibrium (VCE SSCE Chemistry): Flashcards

Extent of reaction at equilibrium

K becomes reciprocal: $K_{reverse} = \frac{1}{K_{forward}}$

K is squared: $K_{doubled} = (K_{original})^2$

K is square root: $K_{halved} = \sqrt{K_{original}}$

Reaction almost complete; products dominate

Very little reaction; reactants dominate

$10^{-4}$ < K < $10^4$; both reactants & products present

Initial, Change, and Equilibrium

Equilibrium concentrations (not initial)

CO has K ~20,000 times larger than $O_2$
