At what temperature does the reaction become feasible? When ΔH = 492.7 kJmol^-1 and ΔS = 542.6 JK^-1mol^-1.

When a reaction is feasible ΔG = 0. Rearrange the equation ΔG = ΔH - TΔS. So that when ΔG = 0, T = ΔH / ΔS. Must convert ΔS from JK^-1mol^-1 to kJK^-1mol^-1 by dividing it by 1000. Then plug in numbers given...

What is the difference between an aldehyde and a ketone, and what type of molecule can they each be reduced to?

Both aldehydes and ketones have a carbonyl functional group (C=O), however in aldhydes the carbonyl carbon atom is the terminal carbon of the chain, whereas in ketones the carbonyl carbon has two alkyl group...

What are the differences between covalent and ionic bonding?

Covalent bonding is the sharing of pairs of electrons between two non-metallic atoms. Ionic bonding is where electrons are transferred from one atom to another, usually from a metallic atom to a non-metallic...

What factors affect the equilibrium position and in what way?

The easiest way to think about this is as the 'law of opposites' Temperature Exothermim reactions: If temp is increased then the reaction moves in the direction to reduce this rise of temp by shifting equili...
