In acidic medium, the rate of reaction between BrO_(3)^(-) and Br^(-) is given by the expression -(d[BrO_(3)^(-)])/(dt)=k[BrO_(3)^(-)][Br^(-)][H^(+)]^(2) It means

Answer»

Rate CONSTANT of the REACTION DEPENDS upon the concentration of `H^(+)` ions.
Rate of reaction is independent of the concentration of the acid added.
The CHANGE in pH of the solution will affect the rate of reaction.
Doubling the concentration of `H^(+)` ions will increase the reaction rate by 4 times.

Solution :Is wrong because rate constant at constant temperature, (b) is wrong because rate depends upon `[H^+]^2`, (c ) is correct be4cause change in pH mense change in `[H^+]^2`, (d) is correct because rate `prop [H^+]^2`.
