A student is doing an experiment to study the rate of reaction between vinegar and Alka-Seltzer. The experiment is done in a film canister. The
reaction produces CO2 gas, which builds up pressure inside the canister and eventually pops the top off. The time it takes to pop the top is what is
used to evaluate the rate of the reaction. In Trial 1, she uses a 1.0 g chunk of an Alka-Seltzer tablet in 10.0 ml of a 0.5 M vinegar solution at 20°C.
The top popped off in 8.34 seconds.
Give a method, other than changing the temperature, to increase the rate of this reaction.
In terms of collision theory, explain why the method chosen causes an increased rate.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
