How many moles of iron (Fe) will be produced from 6.20 moles of carbon monoxide (CO)
anzhelika [568]

Answer:

4.13 moles of Fe will be produced in the reaction

Explanation:

To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.

The reaction is:

Fe₂O₃ + 3CO → 2Fe + 3CO₂

1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.

We assume, the Fe₂O₃ in excess, so we propose this rule of three

3 moles of CO can produce 2 moles of Fe

Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe

Consider the reaction.
vovangra [49]

Answer: The value of Keq for the reaction expressed in scientific notation is  1.6\times 10^{-5}

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.

For the given chemical reaction:

2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)

The expression for K_{eq} is written as:

K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}

K_{eq}=\frac{(1.2\times 10^{-3})^2\times (2.2\times 10^{-3})}{(1.4\times 10^{-2})^2}

K_{eq}=1.6\times 10^{-5}

The value of Keq for the reaction expressed in scientific notation is  1.6\times 10^{-5}
