Suppose that some FeSCN2+ is added to the above solution to shift the equilibrium. When equilibrium is re-established, the follo
kiruha [24]

Explanation:

The given reaction equation will be as follows.

          [FeSCN^{2+}] \rightleftharpoons [Fe^{3+}] + [SCN^{-}]

Let is assume that at equilibrium the concentrations of given species are as follows.

        [Fe^{3+}] = 8.17 \times 10^{-3} M

        [SCN^{-}] = 8.60 \times 10^{-3} M

        [FeSCN^{2+}] = 6.25 \times 10^{-2} M

Now, first calculate the value of K_{eq} as follows.

     K_{eq} = \frac{[Fe^{3+}][SCN^{-}]}{[FeSCN^{2+}]}

              = \frac{8.17 \times 10^{-3} \times 8.60 \times 10^{-3}}{6.25 \times 10^{-2}}

              = 11.24 \times 10^{-4}

Now, according to the concentration values at the re-established equilibrium the value for [FeSCN^{2+}] will be calculated as follows.

             K_{eq} = \frac{[Fe^{3+}][SCN^{-}]}{[FeSCN^{2+}]}

        11.24 \times 10^{-4} = \frac{8.12 \times 10^{-3} \times 7.84 \times 10^{-3}}{[FeSCN^{2+}]}

         [FeSCN^{2+}] = 5.66 \times 10^{-2} M

Thus, we can conclude that the concentration of [FeSCN^{2+}] in the new equilibrium mixture is 5.66 \times 10^{-2} M.

Which law relates to the ideal gas law?
professor190 [17]

<u>Answer:</u> The law that related the ideal gas law is \frac{V_1}{n_1}=\frac{V_2}{n_2}

<u>Explanation:</u>

There are 4 laws of gases:

  • <u>Boyle's Law:</u> This law states that pressure is inversely proportional to the volume of the gas at constant temperature.  

Mathematically,

P_1V_1=P_2V_2

  • <u>Charles' Law:</u> This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

  • <u>Gay-Lussac Law:</u> This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

  • <u>Avogadro's Law:</u> This law states that volume is directly proportional to number of moles at constant temperature and pressure.

Mathematically,

\frac{V_1}{n_1}=\frac{V_2}{n_2}

Hence, the law that related the ideal gas law is \frac{V_1}{n_1}=\frac{V_2}{n_2}
