W(g) + X(g) --> Y(g) +Z(g)
Gases W and X react in a closed, rigid vessel to form gases Yand Z according to the equation above. The initial pressure of W(g)is 1.20 atm and that of X(g) is 1.60 atm. No Y(g) or Z(g) isinitially present. The experiment is carried out at constanttemperature. What is the partial pressure of Z(g) when the partialpressure of W(g) has decreased to 1.0 atm?
A) 0.20 atm
B) 0.40 atm
C) 1.0 atm
D) 1.2 atm
E) 1.4 atm

We can find the partial pressure of Z at a time that we will call the equilibrium using an ICE chart. We identify 3 stages: Initial, Change and Equilibrium and complete each row with the pressure or change in pressure.

W(g) + X(g) ⇄ Y(g) +Z(g)

I 1.20 1.60 0 0

C -x -x +x +x

E 1.20 -x 1.60 -x x x

At equilibrium, the partial pressure of W is 1.0 atm.

1.20 atm - x = 1.0 atm

x = 0.20 atm

The pressure of Z is x = 0.20 atm

The study of chemicals and bonds is called chemistry. There are two types of elements are there and these are metals and bases.

The correct answer is option A) that is 0.20 atm

What is partial pressure?

In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature.
The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture.

Let's consider the following reaction.

W(g) + X(g) ⇄ Y(g) +Z(g)

We can find the partial pressure of Z at a time that we will call the equilibrium using an ICE chart.

We identify 3 stages: Initial, Change, and Equilibrium, and complete each row with the pressure or change in pressure.

W(g) + X(g) ⇄ Y(g) +Z(g)

I 1.20 1.60 0 0

C -x -x +x +x

E 1.20 -x 1.60 -x x x

At equilibrium, the partial pressure of W is 1.0 atm.

[tex]1.20 atm - x = 1.0 atmx = 0.20 atm[/tex]

Hence, The pressure of Z is x = 0.20 atm
