`{:("List I (order)","List II (rate constant)"),((A)"Zero",(p)K=1/(2t)[1/((a-x)^2)-1/a^2]),((B)"First",(q)K=1/(t)[1/((a-x))-1/a]),((C )"Second",(r)k=x/t),((D)"Third",(s)k=1/t"log"_e(1/(a-x))):}`

Text Solution

Verified by Experts

The correct Answer is:
A-r; B-s ; C-q; D-p
Zero order x=kt
First order `K=1/t"In"a/(a-x)`
Second order `K=1/t[1/(a-x)-1/a]`
Third order `K=1/(2t)[1/(a-x)^2-1/a^2]`
