G Which statement about the rate of an SN1 reaction is incorrect? The solvent used can affect the rate of reaction. The concentration of reactants have no effect on the rate of reaction. The temperature can affect the rate of reaction. The strength of the nucleophile has no effect on the rate of reaction.

The concentration of reactants have no effect on the rate of reaction.

Explanation:

The strength of the nucleophile doesn't affect the reaction rate of an SN1 since the nuleophile is not involved in the rate determining step. Increasing the concentration of the substrate (which is a reactant) increases the rate of reaction even though increasing the concentration of the nucleopohile has no effect on the rate of reaction. The use of polar protic solvents assist an SN1 reaction hence the solvent used can affect the rate of reaction. However, temperature affects an SN1 reaction. Increasing the temperature will increase the rate of E1 elimination reaction rather than the SN1 reaction since the both are competing reactions. Lowering the temperature favours SN1 reaction. Hence the answer.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
