Question
Chapter 14, Problem 94SCQ
Interpretation Introduction
Interpretation: Considering the given
Concept introduction:
Isotope: Two atoms are isotopes if they have equal number of protons but with different number of neutrons that is two atoms with same
One of the important applications of isotope is that they are used in isotopic labelling that is they are used as tracers in order to analysis the compound and to find out from which reactant molecule it forms.

(#28) Reaction Rates and time.
A decomposition reaction in the first order has a rate constant of 1.26 x 10-4/sec. If the initial
concentration of the reactant is 0.644 M. how much time will it take before 20% of the reactant has
decomposed?
28a) In blank #1, type-in the working formula to solve for the time required. Enter the algebraic
formula as a one-line equation and without spaces in between characters. Use lowercase for all fonts.
28b) In blank #2, type in your answer for the time it will take for 20% f the reactant to decompose.
