A drop of solution (volume 0.10 ml) contains `6 xx 10^(–6)" mole of "H^(+)`, if the rate constant of disappearance of `H^(+)` is `1 xx 10^(7)" mole litre"^(–1)" sec"^(–1)`. How long would it take for `H^(+)` in drop to disappear ?

Explanation

To solve the problem, we need to determine how long it will take for the `H^+` ions in the drop to disappear, given the concentration and the rate constant. Here’s the step-by-step solution:

### Step 1: Calculate the concentration of `H^+`
We have the number of moles of `H^+` and the volume of the solution. The concentration (molarity) can be calculated using the formula:

\[ \text{Concentration (M)} = \frac{\text{Number of moles}}{\text{Volume (L)}} \]
