Question

Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction, is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially, there are 80 grams of A and 60 grams of B, and for each gram of B, 3 grams of A is used. It is observed that 20 grams of C are formed in 20 minutes. Which of the following statements is TRUE about the order and linearity of the chemical reaction model? Select one: a. Second order linear b. Second order non-linear c. First order non-linear d. First order linear How much of product C is formed in 30 minutes? Select one: a. 23.068 grams b. 20.638 grams c. 26.803 grams d. 28.063 grams e. 27.509 grams f. 20.368 grams What is the limiting amount of C after a long time? Select one: a. 107.60 grams b. 160.67 grams c. 170.60 grams d. 176.60 grams e. 100.76 grams f. 106.67 grams How much of chemical B remains after a long time? Select one: a. 76.67 grams b. 33.33 grams c. None. All of it is consumed d. 36.67 grams e. 36.67 grams f. 66.67 grams
