Question
g. (5pts.) The statement "At equilibrium a system is at the minimum Gibbs' free energy." Is i. Always true i. Always false ili. True provided the minimum is with respect to other states at the same pressure iv. True provided the minimum is with respect to other states at the same temperature and pressure None of the above V. h. (5pts.) Consider a component of a solution that can also exist in the gas above the solution. At equilibrium one variable is the same in the solution and the gas. That variable is i. The activity of the component ii. The concentration of the component iii. The standard state of the component iv. The activity coefficient of the component v. The chemical potential of the component (5pts.) The rate equation for a reaction, A + B = C + D is found to be i. kfa-kbCC. The reaction is probably i. Homogeneous and reversible ii. Heterogeneous and irreversible ii. First order in A iv. Obeying Lanmuir-Hinshelwood kinetics v. Heterogeneous and reversible
Explanation / Answer
g)
True, gibbs fre energy must be near or exactly G = 0
h)
the chemical potential is the same in the liquid and gas phase always, thats why they are in dynamic equilibrium (1 species evaporate, other enters in solution)
i)
if
A+B = C+d
R = KfCa^2 - KbCc
probably heterogenoeus and reversbile since the negative sign
