Miss Angeline Tan writes question require us to compare in terms
of rates of rxn and not extent of rxn
I understand the qn and solution, dont need address this qn
i just thought of this
most of the time, rates of rxn and extent of reaction are
corresponding/correlated/proportional, e.g. rate of rxn increase,
so does extent of reaction
But are they related(as in stems from the same reason/cause, or
are linked to each other)?
are all, or most, rates of rxn increase, extent of reaction also
increase, vice versa?
in this case of reactivity of Halogens with Hydrogen, i think ,
reactivity decreases down group 17, as the H-X bond becomes longer
and weaker, hence both rate and extent of reaction decreases.
i think its ok to discuss abt rate and extent of rxn, for this
qn
