Question
Transcribed Image Text:Some measurements of the initial rate of a certain reaction are given in the table below.
N2 H2 initial rate of reaction
0.215 M 1.76 M
93.0 M/s
0.0694 M 1.76 M
9.69 M/s
0.215 M 3.81 M
436. M/s
Use this information to write a rate law for this reaction, and calculate the value of the rate constant k.
Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol.
rate = k I|
k = 0
Expert Solution
Introduction
The rate of a reaction can be defined as the rate of decrease in concentration of reactants or the rate of increase in concentration of product.
The rate law can be expressed in terms of powers of concentration of reactants, and the reaction constant K.
That is
For this simple reaction
nA→B
Rate = K [A]n
Where n be the order of the reaction with respect to A.
