Question

'A' and 'B' are two different reactants undergoing 1" order decomposition with t½ as 3.0 and 45 minutes respectively. If the initial concentration of "A" and 'B'are in the ratio of 1:2 what is the ratio of the concentrations of "A" and "B"after the time equal to three half lives of "A"?

please don't give other unnecessary answers ​

Answer 1

A and B are two different chemical species undergoing first order decomposition with rate constants K

A

and K

B

which are in the ratio of 3:2, respectively. If the initial concentration of A and B are in the ratio of [A]

0

:[B]

0

=3:2, what would be the ratio [A]:[B] after three half lives of A?
