The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally

Where Z is the frequency factor (frequency of collisions) and ⍴ is the steric factor (deals with orientation of molecules). The value of A must be determined experimentally since it assumes different values for different reactions. It is also dependent on the temperature at which the reaction is taking place.

However Ludwing Fredinand Wilhelmy was considered as the father of chemical kinetics as he was the first who studied the rate of inversion.

Step 1: Find the moles of each element using the equation moles = mass / Mr. Step 2: divide each of the moles by the smallest number calculated. Here, the smallest number of moles is that of oxygen, with 0.025. Step 3: write out the empirical formula using the ratio calculated.

A substance A that changes into another substance may obey a kinetic equation of the form v = k[A], which is a first-order reaction. It is important to recognize that the kinetics of a reaction does not always correspond in a simple way to the balanced chemical equation for the reaction.

Computational chemical engineering involves the development and application of numerical simulation and optimisation technology in order to ultimately improve design, operation and control of complex systems throughout the natural and human-generated world.

Computational chemical engineering could be any computaional technolgy used to solve problems and help chemical engineers design chemical plants. It could be computational process design, computational fluid mechanics or computational heat & mass transfer. using numerical analysis or finite lement methods.

Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.
