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 100 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 5 minutes. Find an equation for the amount of C, x(1), in time /[ Provide a formula with the only variables x and 1- not necessary to solve for x()]
