1000 K 2NO(g) + Br2(g) ⇌ 2NOBr(g) Kc 1.3×10^(-2)

4NOBr(g) ⇌ 4NO(g) + 2Br2(g)

The equilibrium constant for the reaction

2NO(g) + Br2(g) ⇌ 2NOBr(g)

is Kc = 1.3×10^(-2) at 1000 K.

Calculate Kc for

4NOBr(g) ⇌ 4NO(g) + 2Br2(g)

---------------------------------------------------

[참고] 이론적 평형상수 계산

2NO(g) + Br2(g) ⇌ 2NOBr(g)

---> 4NOBr(g) ⇌ 4NO(g) + 2Br2(g)

역반응 & ×2 했으므로,

① 역반응

Kc = 1 / (1.3×10^(-2))

= 76.9

② ×2

Kc = 1 / (1.3×10^(-2))^2

= 5917

또는

Kc = (1.3×10^(-2))^(-2)

= 5917

답: Kc = 5917
