Average rate of a reaction

Explanation

Average rate of a reaction: The charge in the concentratio of any one of the reactants or products per unit time is called average rate of a reaction.
1) `2HI _((g))to H_(2(g))+I_(2(g))`
Rate of reaction `=-1/2 (Delta[HI])/(Deltat)=(Delta[H_(2)])/(Deltat)=(Delta[I_(2)])/(Deltat)`
2) ` Hg_((l))+Cl_(2(g)) to HgCl_(2(g))`
Rate of reaction `=(Delta[Hg])/(Deltat)=-(Delta[Cl_(2)])/(Deltat)=(Delta[Hg Cl_(2)])/(Deltat)`
3) `5 Br_((aq))^(-)+BrO_(3(aq))^(-)+6H_((aq))^(+)to 3 Br_(2(aq))+3H_(2)O_((l))`
Given reaction is
`5 Br_((aq))^(-) +BrO_(3(aq))^(-) +6H_((aq))^(+)to 3 Br _(2(aq))+ 3H_(2) O_((l))`
Rate of reaction `=-1/5(Delta[Br^(-)])/(Deltat)=(-Delta[BrO_(3)^(-)])/(Deltat)=(-1)/(6)(Delta[H^(+)])/(Deltat)=(-1)/(3)(Delta[Br_(2)])/(Deltat)=1/3 (Delta[H_(2)O])/(Deltat)`
