Chlorine gas has a pressure of 1.05 atm at 25°C. What pressure will it exert at 75°C?

It will exert a pressure of 1.23 atm

Explanation:

To calculate the pressure it will exert, we shall be using the Gay Lussac pressure law

Here, we know that pressure and volume are inversely proportional.

Mathematically:

P1/T1 = P2/T2

From the question, P1 = 1.05 atm

P2 = ?

T1 = 25 which when converted to Kelvin scale will be 25 + 273 = 298

T2 = 75 + 273 = 348

Plugging these values, we have;

1.05/298 = P2/348

= P2 = (348 * 1.05)/ 298 = 1.226 which is approximately 1.23 atm
