Interpretation Introduction

Interpretation:

The reason as to why when calcium 47 atoms used in the end is no longer pure is to be stated. The element with which it would be contaminated is to be predicted.

Concept Introduction:

Half-life is defined as the time required for the number of nuclides to reach half of the original value. Half-life is defined as the time required for the number of nuclides to reach half of the original value. The remaining mass of a sample is calculated by the formula shown below.

R=S×(1/2)n

Where,

n is the number of half-lives.

R is the remaining amount of a sample after n half-lives.

S is the initial amount of a sample.

In a cell, the change in entropy (AS) can be calculated from the slope of the E° vs 1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?
Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements:              I. The activation energy (Ea) varies with the temperature of the system.   II. The activation energy (Ea) varies with the concentration of the reactants.        III. The rate constant (K) varies proportionally with temperature.    IV. The value of the…
