When carbon disulfide burns in the presence of oxygen, sulfur dioxide and carbon dioxide are produced according to the following equation. CS2 + 3O2 > CO2 + 2SO2

a. What is the theoretical yield of carbon dioxide if 2.50 mol of oxygen reacts with carbon disulfide? g CO2 (answer should have 1 number after the decimal)

b. Calculate the percent yield of carbon dioxide if 32.4 g were produced. % (answer should have 1 number after the decimal)

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
