Question
Find the reaction order (n), reaction rate constant (k) and reaction rate general form using integral
method.
Integral method steps:
1. Assume a first order reaction (n= 1)
2. Integrate the reaction rate to find CA and time linear relation
3. Plot CA versus time to see if you get a straight line. If not, the assumption is not correct and
assume a second order reaction (n=2), and repeat same procedure till linear plot achieved
I want the full answer and all solution steps for this
Transcribed Image Text:To find the NaOH concentration:
1. Find the number of moles of NaOH used in the second reaction
V NAOH * (1N) * 10 -3 = X Moles
2. Find the initial number of moles of HCl used in the second reaction
20 ml * (1N) * 10 -3 = Y Moles
3. Find the number of moles of HCI reacted with excess moles of NaOH in the second reaction
Y-X = Z Moles
4. Z = number of moles of NaOH unreacted in the second reaction mixture
5. Since the volume of the sample collected is 10 ml, the concentration of the unreacted NaOH is :
CA = Z/ (10 * 10 -3) =
