Two chemicals A and B are combined to form a chemical C. The rate of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially there are 51 grams of A and 19 grams of B, and for each gram of B,1.3 grams of A is used. It has been observed that 17.5 grams of C is formed in 5 minutes.
How much is formed in 40 minutes correctly?
What is the limiting amount of C after a long time correctly?

Please solve using differential equations methods and label parts a, b and c. Thanks Two chemicals A and B are combined to form a chemical C. The reaction is such that it takes 4 grams of A and 6 grams of B to form 10 grams of C. It is observed that 5 grams of C are formed in 10 minutes. Initially there are 50 grams of A and 80 grams of B present. How many grams of C are...
1. Two chemicals A and B react to form another chemical C. The rate at which is formed varies as the product of the instantaneous amounts of A and B present. For each gram of B the reaction requires 2g of A to produce C. 10g of A and 20g of B are present initially; there is no C present initially, and 6g of Care formed in 20 min. (a) Show that æ(t), the amount (g) of C present at...
