Question

Hi can someone please help me with this chemistry problem? I really appreciate it.

The following data was collected for the volume of the O₂ produced in the decomposition of H₂O₂
Calculate the average rate of reactoion for each of the given time interval.

Time	mL O2
0.0	0.0
45.0	2.0
88.0	3.9
175.0	6.8

I would really appreciate steps on how to solve this, so I can finish the rest of the similar problems.
Thank you!

Answer 1

ans)

from above data that

we know that

The average rate of reaction will be =change in volume/time taken for time

By using above table

First we calculate the time between 0 to 45 seconds :

(2.0 - 0.0) / (45 - 0) =

= 0.044 mL / s

next we calculate the time 88 to 45 seconds :

(3.9 - 2.0) / (88 - 45)

= 0.044 mL / s

From time 88 to 175 seconds :

( 6.8 - 3.9) / ( 175 - 88)

= 0.033 mL / s

so finally these are the avereage rate of reaction using above time interval
