JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics

\(X\) ના એક નમૂના ના વિઘટનનો વેગ અચળાંક \(0.05\, \mu g/\)વર્ષ છે, તો \(X\) ના \(5\, \mu g\) ને \(2.5\, \mu g\) માં વિઘટન કરવા માટે કેટલા વર્ષો લાગશે? 

  1. A \(50\)
  2. B \(25\)
  3. C \(20\)
  4. D \(40\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(50\)

Step-by-step Solution

Detailed explanation

According to unit of rate constant it is a zero order reaction then half life of reaction will be \({t_{1/2}} = \frac{{{C_0}}}{{2k}} = \frac{{5\,\mu g}}{{2 \times 0.05\,\mu g/year}} = 50\,years\)
