<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is:
</h3>
<em><u>Solution:</u></em>
Average rate is the ratio of concentration change to the time taken for the change
The concentration of the reactants changes 1.8 M to 0.6 M
here, the time interval given is 0 to 580 sec
Therefore,
Thus option C is correct
First, find the total amount of box tops:
3760 + 2301 + 1855 = 7916
Next find the percent that Mr Aceves class contributed:
3760/7916 = about .47 or 47 percent.
The percent Mrs Bacas class contributed:
2301/7916 = about .29 or 29 percent
The percent Mr Canyons class contributed:
1855/7916 = about .23 or 23 percent.
After, find 47 percent of $600, because Mr Aceves class contributed 47 percent of the total box tops.
.47 * 600 = $282
Next find 29 percent of $600, because Mrs Bacas class contributed 29 percent of the total box tops.
.29 * 600 = $174
Lastly find 23 percent of $600, because Mr Canyons class contributed 23 percent of the total box tops.
.23* 600 = $138
