2. this reaction has reached equilibrium at 40.0 oc, and the total pressure is measured to be 0.363 atm. what is the equilibrium partial pressure of ?

0.242 atm

Explanation:

The reaction is missing. I think this is the original question.

NH₄CO₂NH₂(s) ⇄ 2 NH₃(g) + CO₂(g)

This reaction has reached equilibrium at 40.0°C, and the total pressure is measured to be 0.363 atm. What is the equilibrium partial pressure of NH₃?

Let's consider the following reaction.

NH₄CO₂NH₂(s) ⇄ 2 NH₃(g) + CO₂(g)

We can find the partial pressures at equilibrium using an ICE Chart.

      NH₄CO₂NH₂(s) ⇄ 2 NH₃(g) + CO₂(g)

I                                         0             0

C                                     +2x           +x

E                                       2x             x

The total pressure is the sum of the partial pressures.

P = pNH₃ + pCO₂

0.363 atm = 2x + x = 3x

x = 0.121 atm

The partial pressure of NH₃ is 2x = 2 . (0.121 atm) = 0.242 atm

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
