Chapter 11, Problem 98QAP

Interpretation Introduction

Interpretation:

Four experiments are performed which gives the following data. Some of the data is given and some is missing. Missing data is to be determined.

The observed data is given below-

	Experiment 1	Experiment 2	Experiment 3	Experiment 4
[A]	0.100	0.200	0.300	0.400
catalyst	No	No	Yes	No
temperature	25°C	25°C	25°C	30°C
k (min-1)	0.5		1	0.6
Rate (mol/L.min)
Ea (kJ)	32

Concept introduction:

Relation used to calculate the unknown quantities of experiments is as follows:

For a first order reaction:

$\text{rate}=k\left[\text{A}\right]$

Or,

$k=\frac{\text{rate}}{\left[\text{A}\right]}$

Here, k is rate constant and $\left[\text{A}\right]$ is concentration of the reactant A.
