hey kindly answer me in 2 or 3 sentences abt zero order, 1st order, 2nd order reactions.?

Question

plz tell me how can i distinguish d reactions...so as 2 which orders dey belong...in brief if possible if not..lengthen it..no probs.

Answer 1

the order is just the relationship between the molarity of a reactant and the amount that it affects the rate of the reaction.

Let's say you have the following data:

A + B ---> C

[A]-----[B]------reaction rate
.010----.020-----.050
.020----.020-----.100
.020----.040-----.400

Look at the first and second lines; [A] increases by a factor of 2 as does the reaction rate ([B] is held constant). 2^x = 2? x = 1, so [A] is a first order reactant. Now look at lines 2 and 3; [A] is held constant, [B] increases by a factor of 2, and the reaction rate increases by a factor of 4. 2^x = 4? x = 2, so [B] is a second order reactant.

Now you right the differential rate law like this: rate = k[A][B]^2. The overall order of the reaction is 3.

Answer 2

huh, wha, uh, hmm
