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 40 grams of A and 50 grams of B, and for each gram of B, 2 grams of A is used. It is observed that 15 grams of C is formed in 7 minutes. How much is formed in 14 minutes? (Round your answer to one decimal place.) grams What is the limiting amount of C after a long time? grams How much of chemicals A and B remains after a long time? A grams B grams

Explanation / Answer

2A + B ---> C

amount of C formed after 7 min = 15 g

So, after 14 minutes = 30 g of C would be formed

limiting amount of C = 20 g

After this time, the amount of A remained = 0,

amount of B remained = 30 g
