Which of the following plots is(are) correct for the given reaction?

([P]0[ P{]}_{0} is the initial concentration of PP)

Which of the following plots is(are) correct for the given reaction? ( [ P ] _ 0 is the initial concentration of P )

Options

  1. AThe anodic half-cell of lead-acid battery is recharged using electricity of 0 .05 Faraday. The amount of PbSO _ 4
  2. BThe anodic half-cell of lead-acid battery is recharged using electricity of 0 .05 Faraday. The amount of PbSO _ 4
  3. CThe anodic half-cell of lead-acid battery is recharged using electricity of 0 .05 Faraday. The amount of PbSO _ 4
  4. DThe anodic half-cell of lead-acid battery is recharged using electricity of 0 .05 Faraday. The amount of PbSO _ 4

Correct answer

A. The anodic half-cell of lead-acid battery is recharged using electricity of 0 .05 Faraday. The amount of PbSO _ 4

Step-by-step solution

Which of the following plots is(are) correct for the given reaction? ( [ P ] _ 0 is the initial concentration of P )

this is 1st{1}^{\text{st}} order reaction

For 1st{1}^{\text{st}} T1/2=0.693k{T}_{1/2} = \dfrac{0 . 693}{k}

So independent of initial concentration

Which of the following plots is(are) correct for the given reaction? ( [ P ] _ 0 is the initial concentration of P )

C=C0e−kt⇒tn[CC0]=−kC = {C}_{0}{e}^{- kt} ⇒ tn \left[\dfrac{C}{{C}_{0}}\right] = - k

⇒ln⁡[P[P]0]=−k⇒ \ln \left[\dfrac{P}{[ P{]}_{0}}\right] = - k

So graph DD is incorrect.
