Q_1 From the Exhibit 4‚ U.S. Frasch Sulphur Industry Prices and Profitability‚ 1940-1967‚ we can get the information about the variations in the return on invested capital earned by the industry over the several decades. In sulphur industry‚ the return on invested capital was around 15% from 1940 to 1945. From 1946‚ rate of return began to increase dramatically‚ starting from 16.2 %( 1945)‚ and reached 33.8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29%

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to
