Why do we have to cool the test tube to 100oC before we add the ethanol. The melting point of the product is 258oC.  Why should we not do a mp of the product? The intermediate in brackets loses CO to form the product at 180oC.  If the C=O were replaced by CH2, do you think the same type of reaction would happen with loss of :CH2?

for this reaction R=k[A]-2[B] what happens when you double B? Also what happens when you halve A?

(71) Consider the following reaction. From the given choices of intermediates and/or final products, choose the 5 related to this reaction and put them in order to describe the complete mechanism (all the steps involved) for this reaction.

Please help

(a) Select all of the correct statements about reaction rates from the choices below. 1.The lower the rate of a reaction the longer it takes to reach completion.2 The rate of a reaction is independent of temperature.3 Slow reactions can be speeded up by raising the temperature.4. Reaction rates increase with increasing temperature.5. Solid catalysts do not affect reaction rates.6. Reactions involving very unstable combinations of chemicals have large rate constants.7. A balanced chemical reaction is necessary to relate
