For the same mixture, under the same conditions described in problem 7, calculate keq for 2nh3 (g) n2 (g) + 3h2(g). how is the k
nekit [7.7K]

<u>Answer:</u> The relation between the forward and reverse reaction is K_f=\frac{1}{K_r}

<u>Explanation:</u>

For the given chemical equation:

2NH_3(g)\rightleftharpoons N_2 (g)+3H_2(g)

The expression of equilibrium constant for above equation follows:

K_f=\frac{[N_2][H_2]^3}{[NH_3]^2}         .......(1)

The reverse equation follows:

N_2 (g)+3H_2(g)\rightleftharpoons 2NH_3(g)

The expression of equilibrium constant for above equation follows:

K_r=\frac{[NH_3]^2}{[N_2][H_2]^3}       .......(2)

Relation expression 1 and expression 2, we get:

K_f=\frac{1}{K_r}

Hence, the relation between the forward and reverse reaction is K_f=\frac{1}{K_r}

How many ml of 12.0 M H2S04 are needed to make 500.0 ml of a 1.00 M solution? What happens to the freezing point and the boiling
lora16 [44]

Answer:

41.66 mL of 12.0 M sulfuric acid are needed.

Explanation:

Concentration of sulfuric acid solution taken =M_1=12.0M

Volume of the 12.0 M Solution = V_1

Concentration of required solution = M_2=1.00M

Volume of required 1.00 M solution = V_2=500.0 mL

M_1V_1=M_2V_2 (Dilution)

V_1=\frac{1.00 M\times 500.0 mL}{12.0 M}=41.66 mL

41.66 mL of 12.0 M sulfuric acid are needed.

The freezing point and the boiling point of a solvent when a non-volatile solute is dissolved in it decrease and increase respectively.
