At the time t=0t = 0, some radioactive gas is injected into a sealed vessel. At the time TT, some more of the same gas is injected into the same vessel. Which one of the following graphs, best represents the variation of the logarithm of the activity AA of the gas with time tt?At the time t = 0 , some radioactive gas is injected into a sealed vessel. At the time T , some more of the same gas isAt the time t = 0 , some radioactive gas is injected into a sealed vessel. At the time T , some more of the same gas isAt the time t = 0 , some radioactive gas is injected into a sealed vessel. At the time T , some more of the same gas is

Options

  1. AWhat is the overall reaction for the formation of sodium chloride (NaCl) according to the passage?
  2. BWhat is the overall reaction for the formation of sodium chloride (NaCl) according to the passage?
  3. CWhat is the overall reaction for the formation of sodium chloride (NaCl) according to the passage?
  4. DNone of these

Correct answer

B. What is the overall reaction for the formation of sodium chloride (NaCl) according to the passage?

Step-by-step solution

A=A0e−\lambdatA = {A}_{0}{e}^{- \lambdat}

Take log both side

ℓnA=ℓnA0−λtℓ\text{n}\text{A}\text{=}ℓ\text{n}{\text{A}}_{0} - {\lambda}_{\text{t}}
