Gaseous indium dihydride is formed from the elements at elevated temperature:

3241004551 [841]

<u>Answer:</u>

<u>For 1:</u> The value of $Q_p$ for above reaction is 36.83

<u>For 2:</u> The value of $Q_p$ for above reaction is 36.83

<u>For 3:</u> The equilibrium partial pressure of Indium is 0.126 atm

<u>For 4:</u> The equilibrium partial pressure of hydrogen gas is 0.094 atm

<u>For 5:</u> The equilibrium partial pressure of Indium dihydrogen is 0.018 atm

<u>Explanation:</u>

We are given:

Partial pressure of Indium gas = 0.0650 atm

Partial pressure of hydrogen gas = 0.0330 atm

Partial pressure of Indium dihydride = 0.0790 atm

The given chemical equation follows:

$ln(g)+H_2(g)\rightleftharpoons InH_2(g)$

<u>Initial:</u> 0.065 0.033 0.079

<u>At eqllm:</u> 0.065-x 0.033-x 0.079+x

<u>For 1:</u>

The expression of $Q_p$ for above reaction follows:

$Q_p=\frac{p_{InH_2}}{p_{In}\times p_{H_2}}$

Putting values in above equation, we get:

$Q_p=\frac{0.079}{0.065\times 0.033}=36.83$

Hence, the value of $Q_p$ for above reaction is 36.83

<u>For 2:</u>

We are given:

$K_p$ of the reaction = 1.48

There are 3 conditions:

When $K_{p}>Q_p$ ; the reaction is product favored.
When $K_{p}$ ; the reaction is reactant favored.
When $K_{p}=Q_p$ ; the reaction is in equilibrium.

As, $Q_{p}>K_p$ for the given reaction, the reaction is reactant favored.

Hence, the reaction proceed in the backward direction to attain equilibrium

<u>For 3:</u>

The expression of $K_p$ for above reaction follows:

$K_p=\frac{p_{InH_2}}{p_{In}\times p_{H_2}}$

Putting values in above equation, we get:

$1.48=\frac{(0.079+x)}{(0.065-x)\times (0.033-x)}\\\\x=-0.061,0.835$

Neglecting the value of x = 0.835 because the reaction is going backwards. So, by taking this value, the pressure of the reactants will decrease

So, equilibrium partial pressure of Indium = (0.065 - x) = [0.065 - (-0.061)] = 0.126 atm

<u>For 4:</u>

The equilibrium partial pressure of hydrogen gas = (0.033 - x) = [0.033 - (-0.061)] = 0.094 atm

<u>For 5:</u>

The equilibrium partial pressure of Indium dihydrogen = (0.079 + x) = [0.079 + (-0.061)] = 0.018 atm
