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 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 25 grams of C is formed in 9 minutes. How much is formed in 36 minutes

Answer 1

In 36 minutes, 100 grams of Chemical C is formed.

Step-by-step explanation:

Combination of chemicals A and B = chemical C

Chemical A available = 100 grams

Chemical B available = 50 grams

Proportion of A mixed with C = A2

Proportion of B mixed with C = B1

Therefore, Chemical C = A2 + B1

If 25 grams of C is formed in 9 minutes

In one minute 25/9 grams of C will be formed

Therefore, in 36 minutes, 25/9 * 36 = 100 grams
