Question

Given the reaction : 3I-(aq)+H3AsO4(aq)+2H+aq) 3I3-(aq)+H3AsO4(aq)+H2O(l) a. How is the rate of formation of I3-related to the rate of disappearance of I- b. How is the rate of disappearacne of H+ relatedto the rate of disappearance of I-? Given the reaction : 3I-(aq)+H3AsO4(aq)+2H+aq) 3I3-(aq)+H3AsO4(aq)+H2O(l) a. How is the rate of formation of I3-related to the rate of disappearance of I- b. How is the rate of disappearacne of H+ relatedto the rate of disappearance of I-? b. How is the rate of disappearacne of H+ relatedto the rate of disappearance of I-?

Explanation / Answer

We Know that :          The givenequation is :            3 I-(aq)+H3AsO4(aq)+2H+aq) 3I3-(aq)+H3AsO4(aq)+H2O(l) Rate of the Reaction = - 1 / 3 d [I- ] / dt   = - d [H3AsO4 ] / dt   = - 1 / 2 d [ H+ ] / dt   =   + 1 / 3 d [I3- ] / dt                                  = + d [ H3AsO4 ] / dt   = + d [ H2O ] / dt          a.                    d [ I- ] / dt    =   d [I3- ] / dt    Ignoringthe signs          b.                    d [ H+ ] / dt =   2 / 3 d [ I- ] / dt   Ignoring thesigns.
