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 40s is V₃ - V₂/40
(b) Average rate upto 40s is V₃ - V₂/40-30
(c) Average rate upto 40s is V₃/40
(d) Average rate upto 40s is V₃ - V₁/40 - 20

Answer 1

Answer:pta nahi........

Explanation:

Answer 2

The average rate of reaction will upto 40s will be V₃/40.

The graph will be a straight line till V3 or at t = 40 (Given)

Equation of a line = y = mx + c, where m is the slope to be determined by equation.

m - y2-y1/x2-x1, where (y2-y1) and (x2-x1) are the points on a line

On substituting the value -

V3-V1/t3-t1

Thus, slope = V3/40.
