Question
Chapter 19, Problem 40QAP
Interpretation Introduction
Interpretation:
Interpret the remaining amount of sample after 6 minute if the half life is 1.5 minute.
Concept Introduction:
Half life is the measurement of time required for the conversion of half of the reactant to product and can be indicated as t1 / 2.
A reactant reacts to produce product in particular duration of time whereas if time to be recorded for the completion of half of the reaction then it gets denoted by t1 / 2.
