Consider this reaction: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g).
iragen [17]
Option are as follow,

A. temperature, concentration and surface area 
<span>B. temperature, and concentration only </span>
<span>C. concentration and surface area only </span>
<span>D. temperature and surface area only
</span>
Answer:
           Option-<span>A. Temperature, Concentration and Surface area
</span>
Explanation:

1) Increasing Temperature:
                                              Increase in temperature increases the Kinetic energy of molecules. This results in increase in the velocity and rate of collisions between reactants. Hence, greater the number of collisions between reactants per time greater will be the probability of formation of product per unit time.

2) Increasing Concentration
                                            Increase in concentration results in increase in number of particles of reactants per unit area, hence collision rate increases resulting in rate of reaction.

3) Increasing Surface Area
                                             Grinding of Zn results in the increase of surface area of Zinc. So greater the surface area greater is the exposure of Zinc metal to HCl molecules, hence the rate of formation of product increases.
