Okay, so this is a chemical equilibrium.
00:07
So we have three more hydrogen react with nitrogen gas to produce two more of the ammonia.
00:20
So the question says, the first the reaction is that equivalent.
00:26
But now we try to decrease the pressure and what will happen to the concentration of the hydrogen and ammonia.
00:34
So if we look at this equation, you will find if the reaction go forward, four mores of gas will be converted into two more gas based on the reaction aquarium.
00:55
So from the idea gas law, pv equals to nrt and pressure equals to nrt over v.
01:07
So in such case, since it's in the same volume, if we decrease the mores, the pressure is decreasing.
01:18
So for the reaction, go forward, the pressure will decrease...
