Question

Assertion: Adding more reactants will speed up a reaction.
Reason: The reactants will collide less frequently.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  
• C. Assertion is true but Reason is false
  
• D. Assertion is false but Reason is true
  
• E. Both Assertion and Reason are false
  

Answer 1

Answer: (C)

Assertion is true but Reason is false

$\bullet$ Adding more reactants will increase the rate of the reaction as rate is directly proportional to the concentration of

reactants.

$\bullet$ Increasing the concentration of reactants will increase the frequency of collision.

$\therefore$ Assertion is true but Reason is false.
