Which of the following statements is false?

which of the following statements is false?

a. the rate of second order reactions is dependent on concentration.
b. the rate of a first order reaction is dependent on concentraion.
c. the half life of a second order reaction is not dependent on concentration.
d. the half life of a zero order reaction is dependent on concentration.
e. none of the statements are false.

Option C is false statement. The half life of a second order reaction is not dependent on concentration.

Explanation:

Half life of a reaction is defined as the amount of time which is required for a reactant concentration reduced by half comparison to its initial concentration.

Half life of a second order reaction is depend on the initial concentration of a reaction, in contrast to 1st order reaction.

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).
