For the sequential reactions:
`2A overset(80%)to 3B + C`
`2B overset(50%)to 5D + E`
Moles of A needed for the formation of 1.5 moles of D is:

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:

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)) .

For a sequential reaction : A rightarrow B + C 2B rightarrow C + 2D If % yeild of (i) and (ii) reactions are 90% and 80% respectively, then the overall % yield is expected to be:

A to 2B + C 3B to 2D Find moles of D produced if initially 3 moles of A are taken.
