Kc values - Calculation

The video tutorial explains how to derive the equilibrium constant (KC) for an overall reaction by combining two reversible reactions with their respective equilibrium constants, KC1 and KC2. It demonstrates that the overall KC value is the product of KC1 and KC2. The tutorial applies this rule to specific reactions, showing the calculation of the overall KC value, KC3, by multiplying KC1 and KC2, and confirms the result through cancellation of common terms.

What values are assigned to KC1 and KC2 in the example provided?

What is the final calculated value of KC3 in the example?
