Question
A drop of solution (volume 0.05 ml) contains 3
10–6 moles of H+. If the rate constant of disappearance of H+ is 1
107 mole litre–1 sec–1. How long would it take for H+ in drop to disappear.
- 6
10–8 sec
- 6
10–7 sec
- 6
10–9 sec
- 6
10–10 sec
The correct answer is: 6
10–9 sec
Since rate constant = 1.0 ´ 107 mol litre–1 sec
\ Zero order reaction
For zero order reaction t =
…(I)
Q 0.05 mL has 3 ´ 10–6 moles of H+
\ 1000 mL has
= 0.6 ´ 10–1 mol/litre
\ By equation (1) t =
= 6 ´ 10–9 sec
