Question

Choose the correct option regarding the statements given below:

Statements 1: The rate of the reaction is faster in case of potassium than in the case of magnesium.

Statement 2: Magnesium is more reactive than potassium.

• A. Both statements are correct and statement (ii) is the reason for statement (i).
• B. Statement (i) is incorrect but statement (ii) is correct.
• C. Statement (i) is correct and statement (ii) is incorrect.
• D. Both statements are incorrect.

Answer 1

The correct option is C Statement (i) is correct and statement (ii) is incorrect.

The nature of the reactant plays an important role in the chemical reaction. The more reactive metal reacts faster than that of less reactive metal. Therefore, the rate of reaction is faster in case of more reactive metals. Since potassium is more reactive than magnesium, the rate of the reaction will be faster in the case of potassium.
