Answer : The Lewis-base in this reaction is, water $H_2O$

Explanation :

According to the Lewis acid-base theory,

Lewis acid : It is a substance that can accepts pairs of electrons to form a covalent bond.

Lewis-base : It is a substance that can donates pairs of electrons to form a covalent bond.

The given balanced equation is:

$Fe^{3+}+6H_2O\rightarrow [Fe(H_2O)_6]^{3+}$

In this reaction, $Fe^{3+}$ ion is Lewis-acid and $H_2O$ is a Lewis-base. The $H_2O$ donates electrons to $Fe^{3+}$ ion to form $[Fe(H_2O)_6]^{3+}$ .

Hence, the Lewis-base in this reaction is, water $H_2O$

The question has missing information.

The options are given below.

a.The equilibrium lies far to the right

b. The reaction will proceed very slowly

c. The reaction contains significant amounts of products and reactants at equilibrium.

d. The equilibrium lies far to the left

Answer : The correct answer is option c: The reaction contains significant amounts of products and reactants at equilibrium.

Explanation :

Option a is not correct because for equilibrium to lie far to the right, we need a large value of keq ( Keq >>> 1 ), but the keq value is small.

option b is also not correct because in order to predict the speed of the reaction, we need more information. The speed of the reaction cannot be predicted using Keq value.

Option d is not correct because for Keq to lie far to the left, it has to be very very small. ( Keq <<< 1)

The value of equilibrium constant is given as 4.24. This value is very near to 1.

Equilibrium constant for this reaction is calculated as

$Keq = \frac{[H_{2}] [CO_{2}]}{[H_{2}O][CO]}$

When Keq = 1, $[H_{2}] [CO_{2} ] = [CO] [H_{2}O]$

That means concentrations of products and reactants are equal.

Since the keq value for our reaction is very close to 1, we can say that , there are significant amounts of reactants and products at equilibrium.

Therefore option C is the correct option.

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the react

Elan Coil [88]

Answer: 40.3 L

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles$

$Sb_2O_3+3C\rightarrow 2Sb+3CO$

According to stoichiometry :

1 moles of $Sb_2O_3$ produces = 3 moles of $CO$

Thus 0.600 moles of $Sb_2O_3$ will produce= $\frac{3}{1}\times 0.600=1.80moles$ of $CO$

Volume of $CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L$

Thus 40.3 L of CO is produced.
