Question

At 40.°C, 2.0 mol of hydrogen and 2.00 mol bromine are put in a 2.0L flask and allowed to react according
to the reaction: H2(g) + Br2(l) (double arrow) 2 HBr(g). Kp for this reaction is 1.75x10^2

a. Determine the pressure of HBr at equilibrium.

Pressure =

b. Determine the pressure of hydrogen at equilibrium.

Pressure =

c. Determine the mass of bromine remaining in the flask at equilibrium.

mass =

Expert Solution

Step 1

Ideal gas equation is $P V = n R T$

$P = \frac{n R T}{V}$

Given, Temperature =4 $0^{\circ} C$ = 40+273K = 313K

R = 0.08206 atm/mol K

Volume = 2L
