A mixture of gases containing 0.20 mol of SO2 and 0.20 mol of O2 in a 4.0 L flask reacts to form SO3. If the temperature is 25ºC
diamong [38]

Answer : The pressure in the flask after reaction complete is, 2.4 atm

Explanation :

To calculate the pressure in the flask after reaction is complete we are using ideal gas equation.

PV=n_TRT\\\\P=(n_1+n_2)\times \frac{RT}{V}

where,

P = final pressure in the flask = ?

R = gas constant = 0.0821 L.atm/mol.K

T = temperature = 25^oC=273+25=298K

V = volume = 4.0 L

n_1 = moles of SO_2 = 0.20 mol

n_2 = moles of O_2 = 0.20 mol

Now put all the given values in the above expression, we get:

P=(0.20+0.20)mol\times \frac{(0.0821L.atm/mol.K)\times (298K)}{4.0L}

P=2.4atm

Thus, the pressure in the flask after reaction complete is, 2.4 atm

Which of the following statements is correct about the gases which participate in photosynthesis?
Sidana [21]
If you look at the equation for photosynthesis, it is:
<span>6CO2 + 6H2O + light energy ---> C6H12O6 + 6O2
</span>
Since CO2 (carbon dioxide) is on the left side of the equation, it is being consumed, or used up. Since O2 (oxygen) is on the right side, it is being produced.

The correct answer is the first one, "<span>Carbon dioxide is used up, and oxygen is produced."</span>
