Calculate the standard state gibbs energy of formation
The normal boiling point of liquid bromine is 58.2°C. At 9.3°C the equilibrium vapor pressure of liquid bromine is 100 torr. From this data, calculate the standard state Gibbs energy of formation of bromine vapor at room temperature, ?

On average one customer arrives every 12 seconds at an information kiosk. Arrival times follow a Poisson distribution. What is the probability that less than 5 customers arrive within the next minute?
Two flows of H2O, one of which is saturated vapor at .6 MPa and the other of which is at .6 MPa, 600 deg C, mix adiabatically in a steady-flow process to produce a single outflow at .6 MPa, 400 deg C.

At 1000 K, the total equilibrium vapor pressure over liquid bismuth metal is 4.84 x 10-5 atm. It is known from mass spectrometric experiments that the vapor phase contains both atomic, Bi(g), and diatomic, Bi2(g), species.
