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 9 minutes. how much is formed in 18 minutes? (round your answer to one decimal place.)

30.6 g of C is formed.

Explanation:

2A + B → C

Average rate of reaction = 2[A]/Δt = [B]/Δt = [C]/Δt

Average rate of reaction = [C]/Δt

Average rate of reaction  = 15 g / 9 min

Average rate of reaction  = 1.7 g of C / min

Average rate of reaction = [C]/Δt

[C] = Average rate of reaction x Δt

[C] = 1.7 g of C / min x 18 min

[C] = 30.6 g of C

i think that the answer is c
