Hi regarding the ealier question heres my explanation. Could
someone please help me take a look?
As the concentration of reactants increases, initial rate of
disappearance of ClO3 increases, resulting in a faster rate of
reaction . Using data set from expt 1 and 6 where the concentration
of OH- remains the same and expt 6 has higher cntrcn of
ClO2(0.120mol./dn3) while expt 1 only has 0.020mol/dm3 of ClO2, we
notice that intial rate of disappearance of ClO2 in expt 6 is
faster. By increasing molarity of ClO2 by 6 times, the initial rate
of disappearance of ClO2 increases by 36 times. In expt 1 rate of
disppearance of ClO2 is 0.00276mol/dm3/s while that in 6 is
0.09936mol/dm3/s. On the other hand, increaing cntrn of OH - will
also result in faster rate of disappeance of ClO2. Using data set 1
and 3 where cntrn of ClO2 is the same in both cases at 0.02mol/.dm3
and expt 1 has lower contrn of OH 0 (0.030mol/dm3) than expt 3, at
0.06mol/dm3. Again rate of disappearance of ClO2 for expt 3 at
0.00552mol/dm3/s is faster than 0.00276mol/dm3/s for expt 1
I think I am too long winded and my key points are not well
written. Where did I go wrong in any way?
Later on theres this question
Does the reaction rate depend on the contrntion of ClO2 and OH-
equally? Explain your answer using results from the table. State
which experimental data you are using and show clearly how you
arrived at your answer.
I think its yes and in fact the above explanation i gave seems
more appropriate for this question. Comment on my answer and please
modify wherever necessary Thanks people!
