If you calculate a value for ∆ G ° for a reaction using the values of Δ G f ∘ in Appendix 4 and get a negative number, is it correct to say that the reaction is always spontaneous? Why or why not? Free energy changes also depend on concentration. For gases, how is G related to the pressure of the gas? What are standard pressures for gases and standard concentrations for solutes? How do you calculate ∆ G for a reaction at nonstandard conditions? The equation to determine ∆G at nonstandard conditions has Q in it: What is Q ? A reaction is spontaneous as long as ∆ G is negative; that is, reactions always proceed as long as the products have a lower free energy than the reactants. What is so special about equilibrium? Why don’t reactions move away from equilibrium?

Solution Summary: The author explains that thermodynamics is associated with heat, temperature, and its relation with energy and work. It helps predict whether a process will take place or not.

A laser emits a line at 632.8 nm. If the cavity is 12 cm long, how many modes oscillate in the cavity? How long does it take for the radiation to travel the entire cavity? What is the frequency difference between 2 consecutive modes?(refractive index of the medium n = 1).
