Question

Part A Constants 1 Periodic Table nsider the tollowing reaction and associated uilbriurm constant Find the equilibrium concentrations of A and B for a - 1 and b1. Assume that the initial concentration of A is 1.0 M and thait no B is present at the beginning of the reaction Express your answers using two significant figures separated by a comma. Submit Part B Eind the nqulternum concentrations of A nd r2 and 2 me that the initual concentration of A hat no II in prosent at the beginning of the reaction 10 Mand Express your answers using two significant figures separated by a conma AL,

Explanation / Answer

part A

Kc = [B]^b/[A]^a

2.4 = x/(1-x)

x = 0.706

[B] = x = 0.706 M

[A] = 1-0.706 = 0.294 M

part B

Kc = [B]^b/[A]^a

2.4 = ((2x)^2/(1-2x)^2)

x = 0.3

[B] = 2x = 0.3*2 = 0.6 M

[A] = 1-0.3*2 = 0.4 M

part C

Kc = [B]^b/[A]^a

2.4 = ((2x)^2/(1-x)^1)

x = 0.53

[B] = 2x = 0.53*2 = 1.06 M

[A] = 1-0.53 = 0.47 M
