1. A mixture contains 8.00 g each of O2, CO2, and SO2 at STP. Calculate the volume of this mixture. Which of the gases would exe
1 answer:
Answer:
Explanation:
mole of O₂ =
= .25 moles
mole of CO₂
=
= .1818 moles
moles of SO₂
= .125 moles
Total moles of gas
= .5568 moles.
total volume of gas mixture
= 22.4 x .5568 liter ( volume of one mole of any gas = 22.4 liter)
= 12.47 liter.
gas will exert partial pressure according to their mole fraction
gas having greatest no of moles in the total mole will have greatest mole fraction so
O₂ will have greatest partial pressure.

<u>Answer:</u> The expression for equilibrium constant in terms of concentration is
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by
For a general chemical reaction:
The is written as:
The concentration of pure solids and pure liquids are taken as 1.
For the given chemical reaction:
The expression for is:
In the above expression, magnesium oxide and magnesium carbonate will not appear because they are present in solid state.
So, the expression for becomes:
Hence, the equilibrium constant for the reaction is given above.
