Calculate the values of δg, δf and δsuniv for:
a) vaporization of 39 g of benzene at its boiling temperature (80.1 °c, 1 bar);
b) adiabatic expansion of 0.100 mol of an ideal gas, in vacuo (joule's experiment), with an initial temperature of 300 k, if the initial volume is 2.00 dm3 and the final volume is 6.00 dm3.
note: process a) is reversible, isothermal and isobaric.
data:
r = 8.314 j mol-1 k-1
1bar = 105 pa
m (c6h6) = 78.66 g mol-1

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
