Properties of the Equilibrium Constant
Manipulating a reaction changes its K by fixed rules. Reversing a reaction inverts K (K → 1/K). Multiplying a reaction by a factor n raises K to that power (K → Kn). Adding reactions multiplies their K values (K = K₁ × K₂). These let you build a target reaction's K from known ones.
The trap confuses the manipulation rules — for instance, adding K values when reactions are combined (they multiply), or multiplying K when a reaction is scaled (it takes a power). Reverse inverts, scale exponentiates, add multiplies.

Properties of K

Reversing inverts K, scaling raises it to a power, and adding reactions multiplies K values. The lesson applies the three manipulation rules, then closes with a ten-scenario check.
