평형상수 계산. N2(g) + 3Cl2(g) ⇌ 2NCl3(g) [NCl3] = 1.9×10^(-1) M

 

 

N2(g) + 3Cl2(g) ⇌ 2NCl3(g)

특정 온도에서 평형 혼합물을 분석했더니,

[NCl3] = 1.9×10^(-1) M,

[N2] = 1.4×10^(-3) M,

[Cl2] = 4.3×10^(-4) M이었다.

이 반응의 K를 구하시오.

 

 

For the reaction

N2(g) + 3Cl2(g) ⇌ 2NCl3(g)

An analysis of an equilibrium mixture is performed at a certain temperature.

It is found that

[NCl3] = 1.9×10^(-1) M, [N2] = 1.4×10^(-3) M and [Cl2] = 4.3×10^(-4) M.

Calculate K for the reaction at this temperature.

N2(g) + 3Cl2(g) ⇌ 2NCl3(g)

 

 

 

K = [NCl3]^2 / [N2] [Cl2]^3

= (1.9×10^(-1))^2 / [ (1.4×10^(-3)) (4.3×10^(-4))^3 ]

= 3.24×10^11

 

 

 

답: 3.2×10^11
