Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.There are three important parts to collision theory, that reacting substances must collide, that they must collide with enough energy and that they must collide with the correct orientation.

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed,Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions.The reaction mechanism describes the sequence of elementary reactions that must occur to go from reactants to products. Reaction intermediates are formed in one step and then consumed in a later step of the reaction mechanism. The slowest step in the mechanism is called the rate determining or rate...

Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. ... An important area is the behavior of objects and materials after being placed into a nuclear waste storage or disposal site.Many entities can be involved in nuclear reactions. The most common are protons, neutrons, alpha particles, beta particles, positrons, and gamma rays.

Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

In order to determine a rate law we need to find the values of the exponents n, m, and p, and the value of the rate constant, k. If we are given the reaction orders for a reaction, we have the values of the coefficients we need to write the rate law.Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes...

The rate law is a differential equation, meaning that it describes the change in concentration of reactant(s) per change in time. Using calculus, the rate law can be integrated to obtain an integrated rate equation that links concentrations of reactants or products with time directly.

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon

Intro to stats is simple, even the most inept can do it. College algebra a little more complicated, but with a little extra tutoring, you could still easily get by with a C. You need HS math knowledge, nothing more. But a lot will depend on the teacher.Summary statistics summarize and provide information about your sample data.

Summary statistics summarize and provide information about your sample data. It tells you something about the values in your data set. This includes where the average lies and whether your data is skewed. Summary statistics fall into three main categories: Measures of location (also called central tendency).

Measures of location. Measures of location summarize a list of numbers by a "typical" value. The three most common measures of location are the mean, the median, and the mode. The mean is the sum of the values, divided by the number of values
