Consider the following equilibrium: h2o(g) + co(g) h2(g) + co2(g) a closed container is initially filled with h2o and co. which of the following correctly describes the reaction as it proceeds towards equilibrium?
a. the [co] and [co2] both increase.

b. the [co] decreases and [co2] increases.

c. the [co] increases and [co2] decreases.

d. the [co] and [co2] both decrease.

the answers would be

the first one and the second one

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
