What 3 things drive the pressure of a gas up
Sedaia [141]

Answer:

<h3>Density of the Gas</h3>

Explanation:

More molecules mean more hits against the container walls. Increasing the number of particles means you have increased the density of the gas. This third factor is part of the ideal gas law, which explains how these three factors -- temperature, volume and density -- interact with each other.

The value of the entropy change for the process N₂ (g) + 3H₂ (g) --&gt; 2NH₃ (g) is ________.
kodGreya [7K]

Answer:

negative

Explanation:

Entropy is a measure of the "disorder" in a system.

In this reaction, the amount of disorder decreases. This is because one gas molecule (NH₃) has more order than two gas molecules (N₂ and H₂). Therefore, the entropy change should be negative.
