Answer:
Kc = [N2]*[O2] / [NO]²
Step-by-step explanation:
Step 1: Data given
The balanced equation is 2NO (g) ⇌ N2 (g) + O2 (g)
Step 2: Define Kc
For the equation aA + bB ⇌ cC + dD
Kc =[ C^c] * ]D^d ]/ [A^a]*[B^b]
Step 3: Calculate Kc for this reaction
For the reaction 2NO (g) ⇌ N2 (g) + O2 (g)
Kc = [N2]*[O2] / [NO]²
