The mechanism of a composite reaction consists of a fast pre-equilibrium step with forward and reverse activation energies of 27 kj mol−1 and 35 kj mol−1 , respectively, followed by an elementary step of activation energy 15 kj mol−1 . what is the activation

Explanation:

In this question we have to calculate the activation energy of the mechanism,we know that the mechanism of the reaction consists of pre equilibrium step with forward and reverse activation energies as  27 kJ mol−1 and 35 kJ mol−1 , respectively.

The slowest step is the rate determining step

Activation energy of the over all reaction is

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).
