Gases A, B, C, and D are related by the following reversible reaction: A + B ⇌ C + 2D

Write the expression for the equilibrium constant for this reaction.

At a certain temperature, the concentrations of A, B, and C are 0.54M, 0.34M, and 0.46M, respectively. The Keq for this reaction is 1.6. Find the concentration of D.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
