Asample of gaseous pcl₅ was introduced into an evacuated flask so that the pressure of pure pcl₅ would be 0.50 atm at 523 k. however, pcl₅ decomposes to gaseous pcl₃ and cl₂, and the actual pressure in the flask was found to be 0.74 atm. calculate for the decomposition reaction pcl₅(g) pcl₃(g) + cl₂(g) at 523 k. also, calculate k at this temperature.

Kp = 0.2215

Kc = 0.0052

Explanation:

Step 1: The balanced equation

PCl5(g) → PCl3(g) + Cl2(g)

Step 2: given data

Initial pressure PCl5 = 0.50 atm

Temperature = 523 Kelvin

The actual pressure in the flask was found to be 0.74 atm.

Step 3: Calculate the pressure after the decomposition

Pressure of PCl5 after decomposition = 0.5 - X

Since the equation has a ratio 1:1 the pressure after the decomposition of PCl3 and Cl2 is X

Step 4: Calculate total pressure at equilibrium

0.74 atm = 0.5 atm - X + 2X

X = 0.74 - 0.5 = 0.24 atm

Step 5: Calculate Kp

Kp = P(PCl3)* P(Cl2) / P(PCl5)

Kp = 0.24² / 0.26 = 0.2215

Step 6: Calculate Kc

The ideal gas  wet: P*V = nRT

with P= the pressure of the gas in atm

with V= the volume of the gas in L

with n= the number of moles

with R= the gas constant in L*atm/mol*K

T = the temperature in Kelvin

P= nRT/V

Kp= Kc*(RT)^Δn

Kc=Kp/(RT)^Δn

Kc= 0.2215 / (0.08206*523)^1

Kc= 0.0052

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
