# Vanderwaal real gas constants

Chemistry Level 2

$1. \text{NH}_3 \qquad 2. \text{N}_2 \qquad 3. \text{CH}_{2}\text{Cl}_2 \qquad 4. \text{Cl}_2 \qquad 5. \text{CCl}_4$

Predict which of the above gases have:

(i) the smallest van der Waals "a" constant

(ii) the largest "b" constant.

Concatenate the answer, for an example if gas $$1. \text{NH}_3$$ fits part (i) and gas $$4. \text{Cl}_2$$ fits the part (ii), then enter the answer as 14. For a and b refer van der waal
