Answer:
The correct answer is 23,4375 grams of C.
Explanation:
First, we will identify the limiting reagent, which is the one consumed first. Since each gram of B consumes two grams of A, the product to be consumed first is A.
We calculate the amount of A and B that is consumed in the first 10 minutes is 5 grams of B and 10 grams of A.
Now we calculate the constant that relates the speed of reaction to the amount of reagent in each component.
20 grams of B and 40 grams of A will react completely given the limiting reagent A. We calculate the constant that relates the reaction speed (grams of product/time) with the instantaneous amounts of unconverted A and B. We calculate the constant that relates the reaction speed (grams of product/time) with the instantaneous amounts of unconverted A and B. We calculate the constant that relates the reaction speed (grams of product/time) with the instantaneous amounts of unconverted A and B.
So:
15g/10min = k*(20g*40g)
k=1.5 g/min / 800 g^2
k=1,875 *10^-3 g^3 /min
Now, we calculate the amount of reagent that forms when 20 minutes pass:
x / 10 min = 1,875 *10^-3 g^3/min * (15g * 30g)
x= 8,4375 grams
So we can say that after 20 minutes, 23.4375 grams of C will form.
Have a nice day!
