The accompanying diagram shows how the free energy, G, changes during a hypothetical reaction A(g) + B(g) → C(g) On the left are pure reactants, each at 1 atm, and on the right is the pure product, also at 1 atm.
(a) What is the significance of the minimum in the plot?
(b) What does the quantity x, shown on the right side of the diagram, represent?
Sodium sulfate is gradually added to a solution containing 0.0500 M Ca2 (aq) and 0.0390 M Ag (aq). Explain what will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate
If 2.0 x 10^23 argon atoms strike 4.0 cm^2 of wall per second at a 90 degree angle to the wall moving with a speed of 450 m/s. what pressure (in atm) does the gas exert on the wall
