Question
Need the 3 answers I got wrong. The other two options for the second wrong question are sum and ratio
![Your answer is partially correct.
The reaction of N205 with gaseous H20 is a potentially important reaction in the chemistry of acid rain:
N2O5(g) + H2O(g) → 2HNO3(g)
It is possible to monitor the concentration of N205 with time. Describe a set of isolation experiments from which the rate law and rate
constant for this reaction could be determined.
The isolation method requires that one concentration be substantially smaller than all the others, so the experimental reaction
order follows the order with respect to that one reactant. We are told that it is possible to track the concentration of N205, so this
reactant has to be the one with the
low concentration. Do two experiments; in each, [H2O]o >> [N2O5lo, and with
different
values for [H2O]o. Which graphs do you need to plot to determine order with respect to N205? Select all that apply.
