During hydrolysis of ester is acidic medium ester `+ H_(2)O overset(H^(+))rarr` acid + alcohol rate law is given as r = k[ester] `[H^(+)]` and volume of base used at difference time intervals is given as at pH = 3
`{:("t (in sec)",0,10,oo),(V_(b) "(in mL)",50,100,150):}`
Value of rate constant at 'k' will be :

A

`69.3 sec^(-1)`

B

`6.93 xx 10^(-2)sec^(-1)`

C

`69.3 M^(-1)sec^(-1)`

D

`6.93 xx 10^(-2) M^(-1)sec^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`10 = (0.693)/(k(10^(-3))) rArr k = (0.693)/(10^(-2)) = 69.3 M^(-1)sec^(-1)`

Reaction A + B rarr C + D follows rate law, r = k[A]^(1//2) [B]^(1//2) starting with 1 MofA and Beach. What is the time taken for concentration of A become 0.1 M? (K = 2.303 * 10 ^(-3) )

The decomposition of dimethyl ether leads to the formation of (CH)_(4) and (H)_(2) and (CO) and the reaction rate is given by Rate =(k)[(CH)_(3) (OCH)_(3)]^(3 / 2) The rate of reaction is followed by increase in pressure in a closed vessel, so the rate can also be expressed in terms of the partial pressure of dimethyl ether, i.e., Rate= (k)P (C H)_(3) (OCH)_(3)^(3 / 2) If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
