A graph of volume of hydrogen released ...

A graph of volume of hydrogen released vs time for the reaction between zinc and dil. HCl is given in figure . On the basis of this markt the correct options.

A

Average rate upto `40` s is `(V_(3)-V_(2))/(40)`

B

Average rate upto `40` s is `(V_(3)-V_(2))/(40-30)`

C

Average rate upto `40` s is `(V_(3))/(40)`

D

Average rate upto 40 s is `(V_(3)-V_(1))/(40-20)`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset("Average")(Zn+dil.)HCl to underset("rate")(Zn)Cl_(2)+H_(2)uarr underset("of reaction")`
`=("Change in concentration of" H_(2))/("Change in time")=(V_(3)-0)/(40-0)=(V_(3))/(40)`
