Answer:
1.59 atm
Explanation:
The reaction is:
The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:
we don't include because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of is:
from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of .
The partial pressure of each gas is:
so total pressure is:
replacing the moles we get:
We know that T2=3*T1
replacing this value in the equation we get:
When liquid evaporates we know that it's going from a liquid to a gas therefore going from an ordered state to a more chaotic disordered state meaning the entropy which is the measure of order, goes up. Since this is a spontaneous reaction at high temperatures and non spontaneous at low temperatures and free energy is negative for spontaneous then we can say at high temperatures free energy is negative and at high temps and positive at low temps. Also since evaporation requires energy to evaporate the enthalpy is positive.
