Explanation:

Oxygen is a more reactive non-metal.

There are several parameters to test how reactive an element is. In this case, we are going to use the electronegativity of the two atoms.

Electronegativity is the relative tendency with which atoms of the element attract valence electrons in a chemical bond.

A high electronegativity value suggests more reactivity and a low value implies low reactivity.

On the Pauling's Eelectronegativity table, Oxygen has a value of 3.5 and Phosphorus has 2.1

It implies that oxygen is a more reactive non-metal compared to phosphorus.

Answer:

The calculation and filling of the table based on the ratio indicated by the column is shown on the second uploaded image

1 This is True

2 This is False

3 This is False

4 This is True

5 This is True

Explanation:

Based on your calculations, indicate whether each statement is True (T) or False (F):

Considering the first statement

Looking at the question we can see that the first statement is TRUE this because all the three experiment have different initial concentration (3.5,3.0 & 2.6)

Considering the second statement

Looking at table we can see that the second statement is FALSE because

the ratio value of [NO2]/ [N2O4] in all three experiment have different value 1.4 , 1.5 & 1.7 is not a constant value.

Considering the Third statement

Looking at the table we can see that the third statement is FALSE this is because the ratio value of 2[NO2]/ [N2O4] in all three experiment have different value 2.7, 3.0 & 3.3 is not a constant value.

Considering the Fourth statement

Looking at table we can see that the fourth statement is TRUE this is because the ratio value of $[NO2]^{2}/ [N2O4]$ in all three experiment have same value 3.9, 3.9 & 3.9 is a constant value.
