Answer : The concentration of at equilibrium is 0 M.
Solution : Given,
Concentration of = 0.0200 M
Concentration of = 1.00 M
The given equilibrium reaction is,
Initially conc. 0.02 1.00 0
At eqm. (0.02-x) (1.00-3x) x
The expression of will be,
By solving the term, we get:
Concentration of at equilibrium = 0.02 - x = 0.02 - 0.02 = 0 M
Therefore, the concentration of at equilibrium is 0 M.
The number of hours required : 37.2 hours
<h3>Further explanation</h3>Given
⁴²K (potassium -42)
Required
The number of hours
Solution
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually, radioactive elements have an unstable atomic nucleus.
Based on Table N(attached), the half-life for ⁴²K is 12.4 hours, which means half of a sample of ⁴²K will decay in 12.4 hours
For three half-life periods :
