Explanation / Answer

Part-A

Kc= Kc=[SO2][Cl2] / [SO2Cl2]

according to the Kc eqaution

the balanced eqaution is

SO2Cl2(g) ---------- SO2(g) + Cl2(g)

The answer is 4.

part-B

Kc= {BrCl]^2/[Br2][Cl2]

Br2(g) + Cl2(g) ------------- 2 BrCl(g)

the answer is 2.

part-C

Kc=[CH4][H2O]/[CO][H2]^3

CO(g) + 3 H2(g) -------------- CH4(g) + H2O(g)

the answer is 1.

part-d

Kc=[N2O][H2O]^3/[O2]^2[NH3]^2

2 NH3(g ) + 2 O2(g) -------------- N2O(g) + 3 H2O(g)

the answer is 5.
