Answer:
Your answer would be:
0.98atm.
Explanation:
The pressure of a gas can be calculated by using the following expression:
PV = nRT
P = pressure
V = volume
-----------------------------------
n = number of moles
R = gas law constant
T = temperature
P × 5 = 0.2 × 0.0821 × 298
5P = 4.893
P = 4.893 ÷ 5 = 0.98atm
P = 0.98atm
In conclusion, the pressure of a 5.00 L flask at 25 degrees C. that contains 0.200 mol of Cl2 is 0.98atm.
Have a great rest of your day

Explanation:
The given chemical reaction is:
The relation between Eo cell and Keq is shown below:
The value of Eo cell is:
Br- undergoes oxidation and I2 undergoes reduction.
Reduction takes place at cathode.
Oxidation takes place at anode.
Hence,
F=96485 C/mol
n=2 mol
R=8.314 J.K-1.mol-1
T=298K
Substitute all these values in the above formula:
Answer:
Keq=6.13x10^33
