What affect the rate at which solid and liquid reaction occurs?

Surface area

Explanation:

Surface area affect the rate at which solid and liquid reaction occur because when the surface area is increase, there will be increase in chemical reaction which is as a result of particles size of the solid. When .there is decrease in the particle size of the solid, the surface area will increase and this is as a result of increase in the energy that is required by the particle size.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
