Answer:
0.24 s-1
Explanation:
We first list the parameters as shown in the image attached. The variables are now properly substituted. This equation is used to calculate the rate constant and clearly show us the dependence of the rate constant on temperature. From this equation, we can clearly and easily see that the rate constant increases exponentially with increase in temperature of the reaction system.
Answer:
The Symbols of elements is given by :
IUPAC : International Union Of Pure and Applied Chemistry .
Its is the Universally recognuised organisation which works on Chemical nomenclature and terminology.
Explanation:

Sodium : Na not ''nA' or NA
3.For most of the elements ,The symbol of the element comes from the <u>first two words.</u>
Example : Hydrogen : H
Helium : He
Copper : Cu
Rules for naming elements having mass> 100
1. The names are derived directly from the atomic number .
Ex : 0 = nil 1= un 2=bi 3=tri
2. The name always ends with ''ium''
For example :
102 = Unnilbium
