In the following first order reactions:
`A+ "Reagent" overset(K_(1))(rarr) Product`
`B+ "Reagent" overset(K_(2))(rarr) Product`
The ratio of `K_(1)//K_(2)` when only `50%` of `B` reacts in a given time when `94%` of `A` has been reacted is:

In the following first order competing reactions: A + Reagent rarr Product B + Reagent rarr Product The ratio of K_1/ K_2 if only 50% of B will have been reacted.when 94% of A has been reacted is:

In the following first order reactions (A)overset(k_(1))rarr"product",(B)overset(k_(2))rarr"product" , the ratio k_(1)//k_(2) if 90% of (A) has been reacted in time 't' while 99% of (B) has been reacted in time 2t is :

A consecutive reaction, A overset(K_(1))(rarr)B overset(K_(2))(rarr)C is characterised by:

In the following first order competing reactions A overset(k_(1))rarr B, C overset(k_(2)) rarr D . If only 50% of A have been reacted whereas 94% of C has been reacted in the same time interval then find the ratio of (k_(2))/(k_(1)) .

In the following first order competing reactions A overset(k_(1))rarr B, C overset(k_(2)) rarr D . If only 50% of A have been reacted whereas 94% of C has been reacted in the same time interval then find the ratio of (k_(2))/(k_(1)) .

Consider the following first order competing reactions: X overset(k_(1)) to A + B and Y overset(k_(2)) to C + D If 50% of the reaction of X was completed when 96% of the reaction of Y was completed, the ratio of thoir rate constant ( k_2 // k_1 ) is:

For the consecutive unimolecular first order reaction A overset(k_(1))rarr R overset(k_(2))rarr S , the concentration of component A , C_(A) at any time t is given by

Conisder the following reactions: I. A+B underset(k_(-1))overset(k_(1))hArr C II. C + B overset(k_(2))rarr D Then k_(1)[A][B]-k_(-1)[C]-k_(2)[C][B] is equal to
