Chemical Kinetics Question 325

Question: The half-life for the virus inactivation if in the beginning 1.5% of the virus is inactivated per minute is (Given: The reaction is of first order)

Options:

A) 76 min

B) 66 min

C) 56 min

D) 46 min

Show Answer

Answer:

Correct Answer: D

Solution:

[d] For the first order reaction for small finite change k1=1[A]Δ[A]ΔtΔ[A]/[A]Δt=1.5 % min1

=0.015min1

t1/2=0.6930.015min1=46.2min46mm
