Question

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 mark the correct option.

• A. Average rate upto 40 seconds is $\frac{V_{3} - V_{2}}{40}$
• B. Average rate upto 40 second is $\frac{V_{3} - V_{2}}{40 - 30}$
• C. Average rate upto 40 second is $\frac{V_{3}}{40}$
• D. Average rate upto 40 second is $\frac{V_{3} - V_{1}}{40 - 20}$

Answer 1

Answer: (C)

Average rate upto 40 second is $\frac{V_{3}}{40}$

Answer 2

Average rate upto 40 sec $\frac{V_{3} - V_{0}}{40 - 0} = \frac{V_{3}}{40}$
