Question

For each of the following reactions , indicate if the equilibrium mixture contains mostly products, mostly reactants, or both reactants and products. Part A- H2(g) + Cl2(g) reverse arrows 2HCL(g) Kc= 1.3 x 10 34 power Part B- 2NOBr(g) reverse arrows 2NO(g) + Br2(g)Kc= 2.0 Part C- 2NOCl(g) reverse arrows Cl2(g)+ 2NO(g) Kc = 2.7x 10 -9 Part D- C(g) + H2O(g) reverse arrows CO(g) + H2(g) Kc = 6.3 x 10 -1 For each of the following reactions , indicate if the equilibrium mixture contains mostly products, mostly reactants, or both reactants and products. Part A- H2(g) + Cl2(g) reverse arrows 2HCL(g) Kc= 1.3 x 10 34 power Part B- 2NOBr(g) reverse arrows 2NO(g) + Br2(g)Kc= 2.0 Part C- 2NOCl(g) reverse arrows Cl2(g)+ 2NO(g) Kc = 2.7x 10 -9 Part D- C(g) + H2O(g) reverse arrows CO(g) + H2(g) Kc = 6.3 x 10 -1 Part A- H2(g) + Cl2(g) reverse arrows 2HCL(g) Kc= 1.3 x 10 34 power Part B- 2NOBr(g) reverse arrows 2NO(g) + Br2(g)Kc= 2.0 Part C- 2NOCl(g) reverse arrows Cl2(g)+ 2NO(g) Kc = 2.7x 10 -9 Part D- C(g) + H2O(g) reverse arrows CO(g) + H2(g) Kc = 6.3 x 10 -1

Explanation / Answer

The value of K can indicate if the product favored or the reactant.

if K >> 1 then a product favored

if K << then a reactant favored

Hence,

a) Mixture contains mostly product

b) Mixture contains mostly product

c) Mixture contains mostly reactant

d) Mixture contains mostly reactant
