The reference standard for all of our functions is 1 bar. This problem has you compute values at the old standard of 1 atm in order to assess the difference when producing new standard tables. Consider the vaporization of water at 25 degrees Celsius. Treat the vapor as ideal.
H2O(l) to H2O(g)
Thermodynamic Values at 1 bar standard.
H(l) = -285.83 kJ/mol H(g) = -241.82 kJ/mol
S(l) = 69.91 J/mol-K S(g) = 188.83 J/mol-K
a.)Calculate the equilibrium constant for this process and theequilibrium vapor pressureof water in torr.
b.)Calculate the enthalpy change upon changing the pressure from 1 bar to 1 atm.
c.)Calculate the entropy change upon changing the pressure from 1 bar to 1 atm.

We have to solve only problem 2, I'm sharing Problem 1 only for
reference purpose.
Problem 1. (25 points)
Alice is going to create a notebook including the profile of all
her friends. For each of her friends, she would
like to keep first-name, last-name, cell number, and birthdate
(month and day). At the beginning, she doesn’t
know how many spaces she should reserve for recording her friends,
so she gradually inputs her friends’
information into it.

Problem 1: Simulating Blackjack In this problem we will use
classes and functions to simulate a simplified game of Blackjack
(21). The game begins with a standard deck of 52 playing cards (no
jokers). Each player is dealt two cards to start with. The winner
of a hand of Blackjack is the player whose hand has the highest
value without going over 21.
When calculating the value of a hand, we add up the rank of each
card in the...
