So this question is giving us n2o5, and we're given the graph of it, in a vessel during a certain chemical reaction.
00:11
And we're given the graph where atmosphere, which is the pressure of the n2o5 on the y -axis, and time is on the x -axis.
00:20
And so it's asked, is n2o5 being created or destroyed? so if i look at time zero, i can see that the partial pressure of the n2o5 at time zero was 2 .564 atm at t equals zero.
00:42
And then the partial pressure of n2o5 at 8 seconds is 1 .1521 atmosphere at t equals 8 seconds.
00:57
So we're asked first, is it being created or destroyed? and i really don't like how that's phrased, but we'll work through that.
01:03
So if it's created, then that means that it must be a product.
01:10
And if it's a reactant then that means that it's being consumed or destroyed.
01:16
So if we look at it as a reactant then the partial pressure of n2o5 should go down over time because it's going to be consumed and if instead we look at it as being a product then that means that it should be produced over time so that means it's going to be created.
01:38
So since we look at time equals zero to time equals eight seconds and the partial pressure is decreasing, then that means that it must be a reactant.
01:49
So that means that it's being destroyed, right? because we're using that to create our product...
