Answer: option B) They provide an alternate lower energy mechanism by which the reaction proceeds
Explanation:
Catalyst are involved in chemical reaction increasing the rate they occur by lowering the activation energy found in the bound- reactants complex.
The reaction moves forward because the lower energy mechanism when catalyst are added allows for a more easily splitted bond, thus, allowing the formation of products.
A solute rises the boiling point of a solution, in direct relation with the number of particles added to the solution. Sucrose remains a molecule, does not separate into anything. NaCl gives Na+ + Cl-.
<span>Molar mass of sucrose is 12*12+22*1+11*16=144+22+176=342 </span>
<span>105g sucrose is 105/342=0.3moles ---> 0.3 moles of particles (molecules) </span>
<span>Molar mass of NaCl is 23+35.5=58.5 </span>
<span>35 grams of NaCl is 35/58.5=0.598 ----->0.598*2=1.1974 moles of particles (ions, Na+ and Cl-) </span>
<span>So, 35 grams of sodium chloride in 500 grams of water will have a higher boiling point</span>
Because of the presence of an aromatic ring in benzoyl chloride. Aromatic rings have delocalized pi electrons that imparts unusual stability to the compound. Moreover, it makes it less polar compared to an Acetyl group.
