The Total solution for NCERT class 6-12
A first order reaction has a rateconstant 1.15 10−3 s−1. How long will 5 g of this reactant take toreduce to 3 g?
From the question, we can write down the following information:
Initialamount = 5 g
Finalconcentration = 3 g
Rate constant = 1.15 10−3 s−1
We know that for a 1st orderreaction,
= 444.38 s
= 444 s(approx)
