Question

ZMA(g) arrow Z - 4M - 8B(g)+ ( α -particles) ( α - particles are helium nuclei, so will form helium gas by trapping electron(s)). The radioactive disintegration follows first order kinetics starting with 1 mol of A in a 1-litre closed flask at 27° C pressure developed after two half lives is approximately (A) 24 atm (B) 65 atm (C) 61.5 atm (D) 12 atm

<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-bc9z07t5jplw.png" /> PV=nRT P=(5/2)× (0.082 × 300/1)atm P=61.5 atm

24 atm

65 atm

61.5 atm

12 atm

PV=nRT P=25​×10.082×300​atm P=61.5 atm

$P V = n RT$

$P = \frac{5}{2} \times \frac{0.082 \times 300}{1} a t m$

$P = 61.5$ atm
