A.) Ammonium bisulfide, NH4HS, forms ammonia, NH3, and hydrogensulfide, H2S, through the reaction

NH4HS(s)⇌NH3(g)+H2S(g)

1.)This reaction has a Kp value of 0.120 at 25 ∘C.

What is the initial pressure of H2S(g) in the flask?

Express your answer numerically in atmospheres.

B.) For the reaction

aA+bB⇌cC+dD

the reaction quotient, Q, is given by theexpression

Q=[C]c[D]d[A]a[B]b

under any conditions. The value of Q is equal toKonly at equilibrium.

1.) The following reaction was carried out in a 2.75 L reactionvessel at 1100 K:

C(s)+H2O(g)⇌CO(g)+H2(g)

If during the course of the reaction, the vessel is found tocontain 5.50 mol of C, 15.8 mol of H2O, 3.10 mol of CO, and 7.10mol of H2, what is the reaction quotient Q?

Enter the reaction quotient numerically.

2.)The reaction

2CH4(g)⇌C2H2(g)+3H2(g)

has an equilibrium constant of K = 0.154.

If 7.00 mol of CH4, 4.00 mol of C2H2, and 10.15 mol of H2 areadded to a reaction vessel with a volume of 5.40 L , what netreaction will occur?The reaction

has an equilibrium constantof  = 0.154.

If 7.00  of , 4.00  of , and10.15  of  are added to a reaction vessel witha volume of 5.40  , what net reaction will occur?

	The reaction will proceed to the left to establishequilibrium.
	The reaction will proceed to the right to establishequilibrium.
	No further reaction will occur because the reaction is atequilibrium.

C.)The following reaction was performed in a sealed vessel at748 ∘C :

H2(g)+I2(g)⇌2HI(g)

Initially, only H2 and I2 were present at concentrations of[H2]=3.45M and [I2]=2.40M. The equilibriumconcentration of I2 is 0.0400 M . What is the equilibriumconstant, Kc, for the reaction at this temperature?
