For a reaction Aoverset(k_(r)=0.6M min^(-1))to2B starting with 1 M of 'A' only, concentration of B (in M) after 100 sec. and 200 sec. is respectively?

Consider a reaction A(g)overset(k=0.1 M min^(-1))to2B(g) . If initial concentration of A is 0.5 M then select correct graph.

The substances A(t_((1)/(2))=5" min") and B(t_((1)/(2))="15 min") follow first order kinetics, are taken is such a way that initially [A]=4[B] . The time after which the concentration of both substances will be equal is :

Aoverset(K_(1))toBoverset(K_(2))toC if all the reaction are 1^(st) order and (d[B])/(dt)=0 . Determine [B].

For the consecutive unimolecular-type first-order reaction A overset(k_(1))rarr R overset(k_(2))rarr S , the concentration of component R, C_( R) at any time t is given by - C_(R ) = C_(OA)K_(1)[e^(-k_(1)t)/((k_(2)-k_(1))) +e^(-k_(2)t)/((k_(1)-k_(2)))] if C_(A) = C_(AO), C_(R ) = C_(RO) = 0 at t = 0 The time at which the maximum concentration of R occurs is -
