How is the reaction rate affected by a temperature decrease?

When you lower the temperature, the molecules are slower and collide less. That temperature drop lowers the rate of the reaction. ... That greater density of molecules increases the number of collisions. When you decrease the pressure, molecules don't hit each other.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
