If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?

It doesn't - the reaction rate will not change regardless of how much of that reactant is added. That's the definition of zero-order.

If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
First order; the rate is directly proportional to the concentration of reactant.
Sodium fizzes when added to water. But why doesn't sodium chloride fizz when added to water?
Sodium fizzes in water because it is undergoing a chemical reaction with water to form sodium hydroxide. The result is more stable than either of the original chemicals. When sodium chloride is added to water both of these substances are stable with respect to each other and no reaction occurs that results in a new chemical product.
Why is corrosion considered oxidation?
because when corrosion occours on a metal the chemical reaction is an oxidation. This means that the metal will loose electrons and became a positive ion. Fe ------> Fe 2+ + 2 e- The iron is oxydised from metal to metal ion.
What is Earth in an open system with respect to?
Mainly with respect to energy.
How do you identify rock types?
Rocks are identified by a number of things. Clues lie in its color, mineral composition, size and orientation of grains or crystals, hardness, stratification, layering, banding, density, vesicularity, reaction to acids, fracture, and chemical composition. A website that has a rock identification flowchart is available below.
How is rate of a chemical reaction usually expressed?
Rates of reaction can be expressed depending upon their order.For example say you have a reaction between two chemicals and the initial rate for that reaction is known :-when:-The concentration of one of the reactants is doubled and the other reactants concentration remains the same and the overall rate of reaction does not change - reaction is zero orderwith respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction doubles - reaction is first order with respect to chemical which was doubled.The concentration of one of the reactants is doubled and other reactants concentration remains the same and the overall rate of reaction quadruples - reaction is second order with respect to chemical which was doubled.Zero Orderrate = kFirst Orderrate = k [A] (reaction is 1st order with respect to [A] and 1st order overall)Second Orderrate = k [A][B] (reaction is first order with respect to [A] and first order with respect to[B], reaction is second order overall)rate = k [A]2 (reaction is second order with respect to [A] and second order overall)Orders are simply added together in order to determine the overall order of reaction :-rate = k [A][B][C] would be third order overall and first order with respect to each of the reactantsThere are other orders of reaction, for example 2 and 3 quarter orders and third order reactions, but these are a little more complex.
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
How is the rate of a chemical reaction usually expressed?
Let assume a simple synthesis chemical reaction in solution (the solute is inert for the considered phenomenon). We can write A + B -> C and image to start with a concentration CA and CB of the components A and B and with no molecule of C. At the beginning A and B combine to form C at high speed, since no C is yet present. While the reaction goes on, C start to be present in a certain concentration CC and also the inverse reaction starts to happen, that is C decomposes in A+B. In an instant t, the rates of variation of the concentration of the three substances, that is the quantity of substance produced (or consumed if the rate is negative) in a very small time interval (let us call them RA, RB and RC) follows the so called chemical kinetics laws RA = ki CC - kd CA CB RB=RA RC=kd CA CB - ki CC where the parameters kd and ki are called direct and inverse reaction rates. Their values depends on the microscopic characteristics of the involved molecules, like collision section so on. This is a very simple situation in which the synthesis happens directly by uniting an A molecule with a B molecule. There are much more complicated reactions, where the reaction happens in a set of subsequent states and stoichiometric coefficients different from one are present. For example oxidation of carbon oxide to carbonn dioxide NO2 + CO -> NO + CO2 is a two step reaction, that happens as 1) NO2 + NO2 -> NO3 + NO 2) NO3 + CO -> NO2 + CO2 When a multiple step reaction is present, the rates can always be written, by their dependence from the concentration of the reaction elements is not linear, but depends on some power of the concentrations (that generally has no relation with the original reaction stoichiometry). Also in this case however, the coefficients of such nonlinear dependence are called reaction rates.
How is the law of conservation of mass proved through chemical equations?
Any chemical reaction is correctly writted only if respect this law. The mass of reactants is equal to the mass of products.
What would speed up a reaction?
increasing the concentration of reactants
What happens to a product during a chemical reaction?
The product doesn't exactly provide a role in a chemical reaction, but rather is the result of the chemical reaction occuring. The chemical reaction may occur specifically to produce that product to be used, and it then serves a role in that respect, but generally products don't play a role, but are just the outcome.
How is the effect of concentration changes on the reaction rate seen in the rate?
That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
If you double a concentration of a reactant then the rate of the reaction doubled The order with respect to the reactant is?
First order; the rate is directly proportional to the concentration of reactant.
What is called chemical reaction rate?
The speed of the reaction
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.
