Reversible and Irreversible Reactions starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Reversible and Irreversible Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A reaction is represented as: A + B ⇌ C + D. If the concentration of A is increased, what will happen to the equilibrium position?
A student mixes acetic acid and ethanol and observes the formation of ethyl acetate and water. After some time, the concentrations of all substances remain constant. What type of reaction is this?
Describe how a catalyst affects a reversible reaction.
Describe the difference in energy changes between reversible and irreversible reactions.
Describe the effect of increasing pressure on the equilibrium position of the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g).
Describe the effect of temperature on the equilibrium position of an exothermic reversible reaction.
Describe what is meant by dynamic equilibrium in the context of reversible reactions.
Explain the main difference between reversible and irreversible reactions.
Explain why combustion reactions are generally considered irreversible.
Explain why precipitation reactions are usually irreversible.
Explain why the neutralization of a strong acid with a strong base is considered irreversible.
Explain why the reaction between hydrogen and iodine to form hydrogen iodide is considered reversible.
Explain why the reaction between silver nitrate and sodium chloride is irreversible.
