Answer:
Its pressure will be 0.54 atm at 100 K.
Explanation:
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
Gay-Lussac's law can be expressed mathematically as the quotient between pressure and temperature equal to a constant:

Studying two different states, an initial state 1 and a final state 2, it is satisfied:

In this case:
- P1= 1.75 atm
- T1= 50 °C= 323 K (being 0 C=273 K)
- P2= ?
- T2= 100 K
Replacing:

Solving:

P2= 0.54 atm
<u><em>Its pressure will be 0.54 atm at 100 K.</em></u>

Explanation:
In the first case, when potassium iodide is added to an aqueous bromine solution, a chemical reaction occurs as follows;
Br2(l) + 2 KI(aq) = 2 KBr(aq) + I2(l)
This reaction produces iodine solution which is brown in colour.
Secondly, when potassium iodide is added to aqueous chlorine solution, the following reaction occurs;
2KI(aq) + Cl2(l)→ 2KCl(aq) + I2 (l)
This reaction also yields iodine solution which is brown in colour.
KI(aq) + I2(l) -------->K^+(aq) + I3^-(aq)
The I3^-(aq) solution appears brown at high concentrations.
