Consider the reaction a → b the rate of the reaction is 1.2 × 10−2 m/s when the concentration of a is 0.11 m. calculate the rate constant if the reaction is first order in a. (give units.)

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the correct answer to this question is 2
