Yes, the crystals will have more time to form and therefore are more likely to be larger compared to one that is cooled quickly.
Answer: Please see explanation column for answer.
Explanation: For A two-component mixture containing 1-octene and 1, 4-dimethylbenzene with acetone.
Error----- The retention factor (Rf) is 0.95 and the two spots are coming simultaneously together producing only one spot indicating that that the choice of solvent we have used is too polar. The compounds are interacting rapidly with the very polar solvent and have very low interaction with the stationary phase. than the mobile phase.
Solution:-----, We will need to try other low polar solvent that can allow two spots to be formed on the TLC plate eg is the use of different percentage s of hexane in ethyl acetate ether 10% or 20%.

Answer:</h3>
1. Irreversible Inhibition-Inhibitor may permanently modify an enzyme
2. Irreversible inhibition- Tamiflu, a transition state analog, reversibly binds to neuraminindase
3. Competitive Inhibition-Inhibitor binds reversibly to an enzyme's active
4.Irreversible inhibition-Inhibitor binds to an enzyme at a site other than active site
5. Mixed inhibition-The Al3+ ion binds to acetylcholinesterase or to the acetylcholinesterase- substrate complex
6. Irreversible inhibition-DIPF permanently modifies the hydroxyl group of a Serine residue at the active site
<h3>
Explanation:</h3>
- An enzyme is a biological catalyst that catalysis chemical reactions.
- Enzyme activity is influenced by several factors which include enzyme inhibitors, temperature, and pH among others.
- Enzyme inhibitors are molecules that bind to the enzyme thus interfering with enzyme activity and preventing the binding of substrate to the enzyme.
- Inhibitors may either irreversibly or reversibly bind the enzymes.
- Competitive inhibitors compete with substrates for the active sites while non-competitive inhibitors bind irreversibly to other sites on the enzyme other than the active site.
- Tamiflu is an example of a competitive inhibitor.
- DIPF is an example of a non-competitive inhibitor as it binds the enzyme permanently.
