Question

Which of the following options does not show instantaneous rate of reaction at 40th second? (A) (V5-V2/50-30) (B) (V4-V2/50-30) (C) (V3-V2/40-30) (D) (V3-V1/40-20)

Instantaneous rate can be determinedgraphically by drawing a tangent on the curve.Thus, volume change during 50-30 sec. interval =V5-V2 and not V4-V2. Hence, (V4-V2/50-30) does not show instantaneous rate of reaction at 40th second.

Q. Which of the following options does not show instantaneous rate of reaction at $4 0^{t h}$ second?

$\frac{V _{5} - V _{2}}{50 - 30}$

$\frac{V _{4} - V _{2}}{50 - 30}$

$\frac{V _{3} - V _{2}}{40 - 30}$

$\frac{V _{3} - V _{1}}{40 - 20}$

Instantaneous rate can be determinedgraphically by drawing a tangent on the curve.Thus, volume change during $50 - 30$ sec. interval $= V_{5} - V_{2}$ and not $V_{4} - V_{2}$ . Hence, $\frac{V _{4} - V _{2}}{50 - 30}$ does not show instantaneous rate of reaction at $4 0^{t h}$ second.
