Write a report based on the notes given below.

0.10g glycine and 0.4ml water taken in 5ml conical vessel. Warmed slightly to dissolve the glycine. 0.3ml acetic anhydride added and stirred about 5 minutes. Mixture cooled in the ice bath for 10 minutes. Precipitate collected by suction filtration and washed with a few ml of water. Crystals spread over a piece of filter paper or watch glass and air dried for 10 minutes.
Glycine dissolved after 20 seconds when warmed in glycine water mixture.
White needle-shaped crystals formed when reaction mixture cooled in ice.
0.14gm of solid obtained after filtration and drying of product.
Mp of crystals recorded as 205-207.
Solid product possible still slightly wet.

Conclusion: Crystallized material was in fact acetamilide based on its melting point. Not highly pure. A second crystallization should produce a fairly pure material. But it would also decrease % recovery.

(a) The reaction between hydrogen, H2(g), and nitrogen monoxide, NO(g), has the following rate equation,
rate = k[H2(g)][NO(g)]2,
The overall equation for the reaction is,
2H2(g) + 2NO(g) → N2(g) + 2H2O(l),
and the reaction takes place by a two step mechanism.
(i) What is the meaning of reaction mechanism?
(ii) Explain what a rate determining step is.
iii) Giving your reasoning, write two equations that could describe the two mechanistic steps for the above reaction. It is important to identify the rate determining step.
