Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Answer:
See image attached
Explanation:
Ibuprofen is a chiral compound. 'Chiral' means that it has the ability to rotate plane polarised light owing to the presence of an asymmetrically substituted carbon atom. There are two known stereoisomers of the compound; the S- stereoisomer and the R-stereoisomer. The both are shown using wedge and dash perspectives in the image attached.
Only the S- stereoisomer is active as a drug. The R-stereoisomer is gradually converted into the S-stereoisomer in the body. The drug may also be given as a racemic mixture.
C - rising and cooling, causing water vapor to condense
<span>The ammonia molecules have weaker inter molecular bonds then the hydrogen and nitrogen, this means that the ammonia condensed at a lower temperature so will be a liquid that will be separated from the reaction, while the nitrogen and hydrogen remain as gases so are easy are recycle back into the reacting chamber.</span>
