What does a bidirectional arrow (⇌) tell you about a chemical reaction?Question 5Select one:a.The reaction only occurs in the forward direction.b.The reaction is reversible.c.The reaction only occurs in the reverse direction.d.The reaction cannot occur as written.

Question 10A reversible reaction is a chemical reaction thatMultiple choice question.has a reaction arrow pointing to the left.moves from products to reactants.proceeds very slowly.can occur in both forward and reverse directions.

In a chemical reaction, the products are found on the right side of the arrow.

What does it mean for a chemical reaction to reach equilibrium?Question 6Select one:a.The rates of the forward and reverse reactions are equal. The concentrations of the reactants and products are constant.b.The rates of the forward and reverse reactions are increasing. The concentrations of the reactants and products are equal.c.The rates of the forward and reverse reactions are increasing. The concentrations of the reactants and products are also increasing.d.The rates of the forward and reverse reactions are equal. The concentrations of the reactants and products are also equa

Which of the following statements describes a chemical reaction in equilibrium?Question 6Select one:a.The rate of the forward reaction is equal to twice the rate of the reverse reaction.b.The masses of the reactants and products are equal.c.The concentrations of reactants and products are equal.d.The rates of the forward and reverse reactions are equal.

Which symbol is used to represent a reversible reaction?=⇌→↔2In a reversible reaction, if the forwards reaction is endothermic, what is the reverse reaction?IrreversibleIn equilibriumExothermicEndothermic3If a chemical reaction happens in a container from which none of the reactants or products can escape, what type of system is this?Closed systemSealed systemLocked systemOpen system4The production of ammonia from nitrogen and hydrogen is described by the reversible equation N2 + 3H2 ⇌ 2NH3. Which gases will be present at equilibrium?Nitrogen onlyAmmonia onlyNitrogen, hydrogen and ammoniaNitrogen and hydrogen5When a reversible reaction reaches equilibrium, which of the following statements is not true?The concentrations of all reactants and products remain constantThe forwards and backwards reactions are still happeningThe concentrations of all reactants and products are equalThe forwards and backwards reactions have the same rate of reaction
