Question

In a reaction,5g ethyl acetate is hydrolysed per litre in the presence of dil. HCl in 300 min. If the reaction is of first order, and the initial concentration of ethyl acetate is 22g/L, then calculate the rate constant of the reaction.

Answer 1

yes put your old equation and solve it where are u facing the problem?

Answer 2

@chmvijay Mass is given not the concentration that is the problem

Answer 3

concenteration is what amount of substance per liter of solvent right here also the same that is nothing but g/L =fyou just find it :)

Answer 4

@chmvijay i will try out wait

Answer 5

@chmvijay I am geting the answer as 4.93*10^-3 whereas the answer is supposed to be 8.6*10^-4

Answer 6

can you show ur work up

Answer 7

\[k=\frac{ 2.303 }{ 300 }\log_{10} \frac{ 22 }{ 5 } = 4.9395\times10 ^{-3}\]

Answer 8

@chmvijay

Answer 9

i did it with a calculator.... @Frostbite

Answer 10

22 and 5 are not here the initial and final concentration right

Answer 11

yes i got it

Answer 12

it should be k=2.303/300 log 22/17
since initial concentration is 22g/L
when it hydrolysis in 300 minutes mean the final concentration will be 22-5 =17g/Litre
now you do it you get ur answer :)

Answer 13

@chmvijay genius!! Thanks a lot......are u an iitian?

Answer 14

I am Proud to be an INDIAN :)
