Question

Which factors have the greatest effect on the rate of a chemical reaction between agno3 and cu

Answer 1

Answer:

Surface area of the reactants

Explanation:

If the reactants say Cu is in the powdered form, it reacts very quickly, otherwise the reaction will be delayed

Answer 2

Answer:

Surface Area and concentration

Explanation:

One of the most important factors that affect the rate of chemical reaction is the surface area of reactants. Surface area of reactants has to do with the number of particles of reactants exposed for reaction. In the reaction;

2AgNO3(aq) + Cu(s) -------> Cu(NO3)2(aq) + 2Ag(s), the most important factors affecting the rate of reaction are surface area of the solid copper metal and the concentration of the silver nitrate solution.

If copper turnings are used, the reaction will proceed faster than when a lump of copper is used. This is the effect of surface area in rate of reaction.

The higher the concentration of the solve nitrate solution, the faster the rate of reaction also. Hence the answer.
