How many times will the rate of the elementary reaction 3X + Y → X2Y change if the concentration of the substance X is doubled and that of Y is halved?
  • a)
    r2 = 4r1
  • b)
    r2 = 4.5r1
  • c)
    r2 = 5r1
  • d)
    r2 = 2r1
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
How many times will the rate of the elementary reaction 3X + Y → ...
Since it is an elementary reaction, its rate law r1 = k [A] 3[B]
When the concentrations are changed the new rate will be r2 = k (2[A])3([B]/2) = 4k[A]3[B] 
So, r2 = 4r1.

How many times will the rate of the elementary reaction 3X + Y → ...
To determine the rate of the elementary reaction 3X Y, we need more information. The rate of a reaction depends on the concentration of reactants, temperature, and the presence of any catalysts. Additionally, the rate can be influenced by the stoichiometry of the reaction and the order of the reaction.
