A certain gas occupies a volume of 26L when the applied pressure is 5.7atm. find the pressure in the system when the gas is comp
sergiy2304 [10]
P1 = 5.7atm V1 = 26L
P2 = ? V2 = 6.5 L

By Boyles Law,
P1V1 = P2V2
5.7 × 26 = P2 × 6.5
By solving,
P2 = 22.8atm.

iogann1982 [59]

Answer:

the concentration of PCl5 in the equilibrium mixture = 296.20M

Explanation:

The concept of equilibrium constant was applied where the equilibrium constant is the ration of the concentration of the product over the concentration of the reactants raised to the power of their coefficients. it can be in terms of concentration in M or in terms of Pressure in atm.

The detaied steps is as shown in the attached file.
