The two balanced equations (1) and (2) are for reactions in which gaseous carbon dioxide is produced from the combustion of (1) solid carbon (2) gaseous carbon monoxide.

1. C (s) + O2 (g) CO2 (g) + 94.0 kcal

2. CO (g) + ½O2 (g) CO2 (g) + 67.6 kcal

On the basis of the information given in equation (1) and assuming no change in temperature or pressure, one can correctly conclude that:

A) The rate of reaction is rapid.

B) The total number of moles of products is the same as the total number of moles of reactants.

C) The reaction is exothermic.

D) The weights of the products are greater than those of the reactants.

E) There will be an increase in the volume of the reactants and products taken together as the reaction proceeds.

The correct answer for the question that is being presented above is this one: "E) There will be an increase in the volume of the reactants and products taken together as the reaction proceeds." On the basis of the information given in equation (1) and assuming no change in temperature or pressure, one can correctly conclude that: E) There will be an increase in the volume of the reactants and products taken together as the reaction proceeds.
