Question

Write an expression for the equilibrium constant of each chemical equation: a. SbCl5(g)SbCl5(g) + Cl2(g) b. 2 BrNO(g)2 NO(g) + Br2(g) c. CH4(g) + 2 H2S(g)CS2(g) + 4 H2(g) d. 2 CO(g) + O2(g)2 CO2(g)

Answer 1

Answer:

See explanation

Explanation:

Step 1: Data given

For the reaction aA + bB ⇆ cC + dD

Kc = [C]^c * [D]^d / [A]^a [B]^b

a. SbCl5(g) ⇄ SbCl3(g) + Cl2(g)

Kc = [Cl2]*[SbCl3] / [SbCl5]

b. 2 BrNO(g) ⇄ 2NO(g) + Br2(g)

Kc = [Br2]*[NO]² / [BrNO]²

c. CH4(g) + 2 H2S(g) ⇄ CS2(g) + 4 H2(g)

Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]

d. 2CO(g) + O2(g) ⇄ 2CO2(g)

Kc =  [CO2]² / [O2][CO]²
