\(X\) का विघटन \(0.05 \mu g /\) वर्ष का दर नियतांक प्रदर्शित करता है। \(X\) के \(5 \mu g\) को विघटित होकर \(2.5 \mu g\) होने में कितने वर्ष लगेंगे?

  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 \({t_{1/2}} = \frac{{{C_0}}}{{2k}} = \frac{{5\,\mu g}}{{2 \times 0.05\,\mu g/year}} = 50\,years\)
