In the reaction
`BrO^(-3)(aq) + 5Br^(-) (aq) + 6H^(+) rarr 3Br_(2)(1) + 3H_(2)O(1)`
The rate of appearance of bromine `(Br_(2))` is related to rate of disapperance of bromide ions as folllwoing :

Consider the following reaction in aqueous solution 5Br^(-) (aq) + BrO_(3)^(-) (aq) + 6H^(+)(aq) to 3Br_(2)(aq) + 3H_(2)O(l) If the rate of appearance of Br_(2) at a particular time during the reaction is 0.025 M"sec"^(-1) , what is the rate of disappearance (in "Msec"^(-1) ) of Br^(-) at that time?

In the reaction Bromine 3Br_2 + 6 OH^(-) rarr 5 Br ^(-) + BrO_3^(-) + 3H_2O

In the ions equatio, BrO_(3)^(-) + 6H^(+) + xe^(-) rarr Br^(3+) + 3H_(2)O , the value of x is
