Answer: oprion <span>A. Catalysts can only increase the rate of reaction for compounds that do react.

Explanation:
Such as the right choice states a catalyst cannot make react two materials that cannot chemically react.
The catalysts modify the rate (speed) of a reaction between chemicals.
The definition of catalyst is a substance that increases the speed of a chemical reaction by modifying the activation energy but that is not consumed in the reaction.
Then three facts must be highlithed about catalyst:
1) Catalysts are not included in the chemical equation since they do not increase the amount of product that can be obtained (they do not change the theoretical yield of the reaction).
2) Catalysts change the path that the reactants take to yield the products, which is how the energy activation is changed.
3) As consequence, catalysts are not consumed during the reaction.
The balanced chemical reaction is:
<span>C6H12 + 9O2 = 6CO2 + 6H2O
We are given the amount of </span><span>C6H12 to be used for the reaction. THis will be the starting point for the calculations.
1.900 g </span>C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol CO2 / 1 mol <span>C6H12) (44.01 g /mol ) = 5.96 g CO2
</span>1.900 g C6H12 ( 1 mol C6H12/ 84.18 g C6H12) ( 6 mol H2O / 1 mol <span>C6H12) (18.02 g /mol ) = 2.44 g H2O
