Which answer does not describe the following reaction? no (g) + o2 (g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. 2 no2 (g) (1) the reaction is in dynamic equilibrium. (2)the reaction does not go to completion. (3)the reaction is reversible. (4)the concentration of reactants and products will be equal.

“(4) The concentration of reactants and products will be equal” does not describe the reaction.

2NO(g) + O₂(g) ⇌ 2NO₂(g)

The concentrations will almost certainly not be equal.

The reaction is a reversible dynamic equilibrium. There is always some NO and NO₂ present at equilibrium, so the reaction does not go to completion.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
