प्रश्न
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.
पर्याय
Average rate upto 40s is `(V_3 - V_2)/40`
Average rate upto 40 seconds is `(V_3 - V_2)/(40 - 30)`
Average rate upto 40 seconds is `V_3/40`
Average rate upto 40 seconds is `(V_3 - V_1)/(40 - 20)`
MCQ
उत्तर
Average rate upto 40 seconds is `V_3/40`
Explanation:
Average rate for the reaction = `("Change in concentration of" H_2)/"Change in time"`
= `"Final concentration - Initial concenrtation"/"Final time - Initial time"`
Analyzing the graph line where time and vloume intersect.
= `(V_3 - 0)/(40 - 0)`
= `V_3/40`
