Complete Question
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 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
