A reaction is represented by this equation:
2W(
aq
) ⇌ X(
aq
) + 2Y(
aq
)
K
c
= 5 × 10
−4
(a) Write the mathematical expression for the equilibrium constant.
(b) Using concentrations of ≤1
M
, make up two sets of concentrations that describe a mixture of W, X, and Y at
equilibrium.
(a) The mathematical expression for the equilibrium constant is written as:
Kc = [X]^1 * [Y]^2 / [W]^2
In this equation, [X], [Y], and [W] represent the concentrations of X, Y, and W respectively.
(b) To create two sets of concentrations that describe a mixture of W, X, and Y at equilibrium, we can assign arbitrary concentration values within the range of ≤1 M for each substance. Here are two examples:
Set 1:
- [W] = 0.05 M
- [X] = 0.01 M
- [Y] = 0.02 M
Set 2:
- [W] = 0.1 M
- [X] = 0.02 M
- [Y] = 0.04 M
Remember, these are just examples and you can choose any other concentrations within the given range (≤1 M) as long as they follow the stoichiometry of the equation.
