Answer:

instantaneous rate at 40 s= 0.0035 M /s.

Explanation:

Instantaneous rate at 40 s is the slope of the line (tangent to the curve)

=  Δp/Δt

From, the straight orange line

ΔP = (0.48 - 0.16) M.

Δt = (92 -0) s

Now, instantaneous rate at 40 s

=  0.48 - 0.16/92 - 0

instantaneous rate at 40 s= 0.0035 M /s.

0.0035
