If there is Block of zinc, only the zinc on the surface gets exposed to the other reactants but if there is granulated zinc because of its more surface area the zinc is more exposed so the granulated zinc is used for the greater reaction rate.

Why do you think that granulated zinc is used instead of a block?
Granulated zinc is used instead of a block as the surface area of granulated zinc is much more than that of a block. Hence it's easier for it to react with oxygen if the area is more. This is why it's used.
Chemical equation for granulated zinc and diluted sulfuric acid?
The Chemical equation for granulated zinc and diluted sulfuric acid is Zn + H2SO4 GIVES(arrow) ZnSO4 + H2O And impurities like arsine (AsH3), phosphine (PH3), CO2, SO2, H2O(gas.) and H2S because granulated zinc has impurities.
What are the products formed when granulated zinc reacts with caustic soda?
lund
Why copper Iron and Lead are commonly used around the world in construction for pipes and in electrical wiring. Why are these used instead of Zinc and Magnesium?
Zinc and magnesium are too reactive.
Uses of zinc?
Zinc is an important ingredient in traditional dry cell batteries and is also widely used to cover steel to reduce corrosion of the steel by sacrificial corrosion of the zinc instead. The latter effect may be achieved by cathodic protection as well as by direct contact between steel and zinc.

Why granulated zinc is used in the preparation of hydrogen rather than metallic zinc?
Don't know, because granulated zinc IS metallic itself: solid, elemental Zn.
Why is granulated zinc preferred for lab preparation of hydrogen?
granulated zinc is therefore preferred . it contains traces of copper as an impurity witch catalyses the reaction and prevents the deposition of the gas on zinc
Why granulated zinc is preferred to metallic zinc in the preparation of hydrogen using dilute acid?
Granulated zinc has more surface area exposed to the acid, so the reaction can occur more rapidly.
