Question

The rate of the reaction in terms of the "appearance of product indudes the change in the concentration of the product, the time interval, and the coefficient of the product Consider the following reaction 2A +3B+3C+ 2D The concentrations of product Cat three difent tine intrvals are given Use the tollwing data to determine the rate of reacion in terms of te appearance of product C between time 0 s and time 20s Time (s) 020 40 (M)| 0 000 | 00120100240 Express your answer in molar concentration per second to three significant figures. View Available Hint(s) M. : The rate of reaction

Explanation / Answer

rate of change of C = ([C]2 - [C]1)/(t2-t1)
= (0.0120 - 0.000) / (20 - 0)
= 6.00*10^-4 M/s

from given chemical reaction,
rate of reaction = (1/3)*rate of change of C
= (1/3)*6.00*10^-4 M/s
= 2.00*10^-4 M/s
Answer: 2.00*10^-4 M/s
