The rate of the reaction between two reactants X and Y can be expressed as R = k [ X ]^2[ Y ] . In an experiment, the initial rate of the reaction was found to be R ₁ when the initial concentrations of X and Y are [ X ₀ ] and [ Y ₀ ] . Another experiment was performed in which [ X ₀ ] was taken as 1 / 2 [ X ₀ ] . What should be [ Y ₀ ] in this experiment to get the initial rate as 0.5 R₁ ?

Options

  1. A4 [ Y ₀ ]
  2. B1 / 2 [ Y ₀ ]
  3. C2 [ Y ₀ ]
  4. D[ Y ₀ ]
