Question

Consider the data below for a reaction A
B
Time
(sec)
0 10 20 30
Rate 1.60x10° 1.60x1021.60*10*1.59x102
From the above data the order of reaction is
(1) Zero
(2) 1
(3) 2
(4) 3​

Answer 1

Answer:zero

Explanation: In a reaction concentration of a reactant decreases with increase in time. And in all reaction except zero order reaction rate depends on concentration of the reactant so it changes with the change in concentration of reactant or with change in time but here rate of the reaction is independent of time. Therefore it is a zero order reaction.

Answer 2

Answer:

zero order rxn

Explanation:

"Reaction in which the concentration of reactant do not change with time are said to be Zero order rxn"

And we also know that rate of rxn is directly proportional to concentration of reactant

Now According to given table rate does not changing with time which shows Zero order rxn
