What would increase the reaction rate?

Enzymes can increase the rate of a reaction by lowering the activation energy needed for the reaction

Catalyst would increase the reaction rate.

Explanation:

The rate at which the chemical reaction occurs is controlled by a number of factors and catalyst is the most suitable answer because irrespective of the type of reactants involved and the type of reaction, a catalyst always increases the speed of the reaction no mater what as it is independent. Other factors which influences the reaction rate are temperature, increasing the concentration of the reactants, e.t,c.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

answer; how far out of place which the object finished relative to the starting location;
