The complete question is shown on the first uploaded image

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.

Considering the Fifth  statement

Looking at table we can see that the fifth statement is TRUE this is because

each having different set of Equilibrium concentration
