During equilibrium, the rates of the forward and the reverse reaction are ________

unequal for exothermic reactions

unequal for endothermic reactions

What is the proper K eq for the following reaction? 2 NO (g) + O 2(g) ⇌ 2 NO 2(g)

K eq = [NO 2 ] 2 / [NO] 2 [O 2 ]

K eq = [NO] 2 [O 2 ] / [NO 2 ] 2

Given the equation representing a reaction: N 2 O 4(g) ↔ 2NO 2(g) Which statement describes this reaction at equilibrium ?

The concentration of N 2 O 4 (g) and the concentration of NO 2 (g) must be constant.

The concentration of N 2 O 4 (g) must equal the concentration of NO 2 (g).

The rate of the forward reaction is greater than the rate of the reverse reaction.

The rate of the reverse reaction is greater than the rate of the forward reaction.

There are more products than reactants when the reaction reached equilibrium.

There are more reactant than products when the reaction reached equilibrium.

The amount of reactants is equal to the amount of products.

Le Chaltelier's Principle states that if a chemical system at equilibrium is stressed,

the system will adjust to reduce the stress

the system will adjust to increase the stress
