Which is better solvent: water or carbon tetrachloride?

To know which is a better solvent between the two, one should know what will be the solute. It really depends on what type of solute you have. If the solute is polar then water is the better solvent for that type of solute. However, when the solute is a nonpolar substance then carbon tetrachloride is the better solvent.

Okay this will take 1 hour okay dont forget me.

The higher the temperature, the increased rate constant for a reaction.(positive linear association)
