Chemical reactions. The number of electrons in an atom's outermost valence shell governs its bonding behavior. Therefore, elements whose atoms can have the same number of valance electrons are grouped together in the periodic table of the elements.
Answer
The most abundant carbon isotope is carbon-12
Explanation:
The relative atomic mass of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass of carbon.
In fact, the C-12 isotope makes up 98.9% of carbon atoms, C-13 makes up 1.1% of carbon atoms, and C-14 makes up just a trace of carbon atoms as they are found in nature.
The reaction rate of a chemical reaction is determined by the slow step in the reaction mechanism.
The rate ii given by the product of the species of the determining step, each raised to its coeeficient in the chemical reaction that represents this step.
So, given that the determining step is represented by A + 2B→C, the reaction rate is r = k[A]*[B]^2.
This mechanism is verified becasue the total order is the summ of the coefficientes : 1 + 2 = 3 and the exponent 2 makes B is a bigger rate determinant than A.
So, the answer is the option b. k[A][B]^2.
