Question

On the basis of given graph, correct increasing order of reactions?

Answer 1

Following graph is obtained for four different reactions [ see graph ]

on the basis of above graph, correct increasing order of reaction is .....

solution : rate of reaction is r = [X]ⁿ , where [X] is concentration of reactants and n is no is order of reaction.

now take log both sides we get,

log r = n log [X]

here it is clear that if draw graph between log [rate ] and log [ conc. ] , then slope of line shows the order of reaction.

i.e., higher the slope, higher the order of reaction.

we see that angles made by D, C, B and A with positive x - axis are ..

A > B > C > D

so, order of reaction is D < C < B < A .i.e., correct option is (2)
