The value of the equilibrium constant for the combination of nitrogen and oxygen to make NO is 2 x 10-9. What does this tell you about the concentrations of materials in the equilibrium mixture?

Answers

Answer: The reaction must proceed in the reverse direction.

Explanation:

$K_p$ is the constant of a certain reaction at equilibrium while $Q_p$ is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

$N_2(g)+O_2(g)\rightleftharpoons 2NO(g)$

The expression of $K_p$ for above equation follows:

$K_p=((p_(NO))^2)/(p_(N_2)* p_(O_2))$

We are given:

$K_p=2* 10^(-9)$

There are 3 conditions:

When $K_(p)>1$ ; the reaction is product favored.

When $K_(p)<1$ ; the reaction is reactant favored.

When $K_(p)=1$ ; the reaction is in equilibrium.

As, $K_p<1$ , the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.

Hence, the reaction must proceed in the reverse direction.

If you use 19 mL of 0.100 M KMnO4, how many moles have you used? The answer has to be in four decimal places (do not forget the leading zero). No scientific notation.How much 5.0 M H2SO4 needs to be used to make 152 mL of 1.0 M? Round answer to nearest whole number and omit units.

Answers

1)

Volume = 19 / 1000 = 0.019 L

n = M * V

n = 0.100 * 0.019

n = 0.0019 moles
__________________________

2)

M₁ * V₁ = M₂* V₂

5.0 * V₁ = 1.0 * 152

5.0 V₁ = 152

V₁ = 152 / 5.0

V₁ = 30.4 mL
