<p>The 2003 was released exam, but unfortunately I can't find the answers for the part twos. Does anybody know where I can find these to check my work?</p>
<p>I will attempt to do it, and tell you what I get.</p>
<h1>2</h1>
<p>(a) 8.56 atm
(b) (i) 1/2; (ii) 4.28 atm
(c) Decreases, because N2 has smaller molar mass than O2, so it effuses more quickly (the rate of eff is inversely prop to the sqrt of molar mass), so more N2 escapes than O2, lowering ratio.
(d) 2NO + O2 --> 2NO2
(e) 0.861 atm</p>
<p>I'm not by any means sure of those answers, but that's what I got ^_^</p>
<p>thanks for your help</p>
