What does chemical equation mean? The activation energy, Ea, for a particular reaction is 37.8 kJ/mol. If the rate constant at 280 K is 0.178 M/s, what is the value of the rate constant at 457 K? (R = 8.314 J/molK) How to calculate the rate of reaction in chemistry?
What does chemical equation mean? What is the product of the following reactions in the diagram below? How do reactants and products participate in a chemical reaction? In the respiration equation, does energy act as a reactant or a product? How do you write a chemical equation with no re...

The larger the value of Ka, the higher the product:reactant ratio. That’s to say, the higher the value of Ka, the more free protons there are in the solution. This, by definition, means the larger the value of Ka, the stronger acid we are dealing with. Remember—stronger acids...
Computational Chemistry Molecular Modelling Statistical Mechanics 1Introduction The general framework to describe and predict the behavior of macroscopic matter, statistical mechanics, was laid down in the 19th century by Boltzmann and Gibbs. The first ingredient of this theoretical framework is the atomisti...
Interviewer: So, where does the gasoline go? John: The gasoline is used up by all the parts. It’s also exhausted. It’s exhausted through the gas pipe or the exhaust pipe I mean. And it goes back into the air. Interviewer: Ok. So do you think the car needs the energy in order...
(chemistry) To change the direction of a reaction such that the products become the reactants and vice-versa. Flip To resell (an asset) rapidly to make a quick profit. Reverse To place (a set of points) in the reverse position. Flip To become insane or irrational; - often used with ...
Formulating Chemistry Equations In a chemical equation, reactants are listed on theleft side of the arrow, while products are on the right side. If a chemical reaction has an arrow that points both left and right, then substances on both sides of the arrow are reactants as well as produc...
rate proportional to the square of the reactant's concentration (rate = k[A]2) or both reactants are consumed linearly over time (rate = k[A][B]). The units of the rate constant,k, of a second-order reaction are M-1·s-1. In general, second-order reactions take the form:...
