Answer
(a) produces the greatest amount of products.
It produces 2 $CO_2$ molecules.
Work Step by Step
1. Count the amount of each reactant in each diagram:
a. 3 $CH_3OH$ and 3 $O_2$
b. 1 $CH_3OH$ and 6 $O_2$
c. 4 $CH_3OH$ and 2 $O_2$
2. Determine the amount of $CO_2$ each diagram will produce.
a. 3 $CH_3OH$ produce 3 $CO_2$, and3 $O_2$ produce 2 $CO_2$. Therefore, this mixture will produce 2 $CO_2$.
b. 1 $CH_3OH$ produces 1 $CO_2$, and 6 $O_2$ produce 4 $CO_2$. Therefore, this mixture will produce 1 $CO_2$.
c. 4 $CH_3OH$ produce 4 $CO_2$, and 2 $O_2$ produce 0.7 $CO_2$. Therefore, this mixture will produce 0.7 $CO_2$.
3. The one that produces the greatest amount of products is (a).
