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

answera compound;

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
