How does the rate of change of product concentration compare to the rate of change of reactant concentration?

It is the ratio of the concentrations of products to the concentrations of reactants.

A ---> B
then the rate of disappearance of A is exactly equal to the rate of appearance of B.
However, if the balanced reaction was
2A ---> B
then the rate of disappearance of A would be exactly double the rate of appearance of B, because 2 A's have to be consumed to make 1 B.
Said in general terms, for a reaction:
aA + bB ---> cC + dD
rate = 1/a * -d[A]/dt = 1/b * -d[B]/dt = 1/c * d[C]/dt = 1/d * d[D]/dt
where lower-case letters are the coefficients of the balanced reactions, upper-case letters are the species involved in the reaction, and square brackets means the concentration of whichever chemical is inside.

Added:Yes, this is a very fine definition of what an equilibriumactually is: dynamic, going both sides (forward and backward), at the same time, at the same rate.The effect is that all concentrations (Products and Reactants) are constant, remain the same.

∙ 12y agowhen concentration is increased to reactants - the forward reaction increases and backward reaction decreases.
when concentration of product is increased - forward reaction decrease and backward reaction increases

When the speed at which a reactant will change to product is proportional?
Perhaps you are referring to a first order reaction.
When substances change into new substances what is it called?
This substance is called "reactant" or "initial product".
Why is it essential to use balanced chemical equations when determining the quantity of a product fo?
It should represent a true chemical change. It should be balance it should be molecular all the reactant and product must be written in term of there respective chemical formula.
How do you calculate an equilibrium constant?
Kp = (P-product)(P-product) --------------------------- (P-reactant)(P-reactant) its always products over reactants, you can always re-arrange the formula to find the pressure of one of the products or reactants.
What is initial rate?
The initial rate refers to the rate at which a chemical reaction occurs at the beginning, when the reactants are first mixed together. It is determined by measuring the change in concentration of a reactant or product over a short period of time immediately after the reaction has started.
The speed at which a reactant will change to a product is proportional to its?
molecular concentration
Why amount of reactant and product do not change in a reversible reaction?
This is the law of mass conservation.
Why is fire chemical change'?
Fire is Combustion, in which your reactant is reacted with oxygen and heat to form carbon dioxide and water, so you turn your reactant into a product this is a chemical change.
When the speed at which a reactant will change to product is proportional?
Perhaps you are referring to a first order reaction.
When substances change into new substances what is it called?
This substance is called "reactant" or "initial product".
Which way would a reaction shift with the addition of HCL?
it depends if it is on the reactant side or product side. BUTTT in this case, I am assuming HCL is a solid.which whether or not it is on the reactant or product side, there would be NO CHANGE.
Why does substance's volume change when it goes through a chemical change?
When reactants are converted into products some amount of reactant actually do not get converted into product. This is the case in any process. Total conversion of reactant species into product species is never possible.
How does a system at equilibrium respond to the addition of more reactant or Product?
Le Chetalier's Principle states "If to a system in equilibrium, a change is applied, the system will react to tend to negate that change" - or the substance of that statement. So if you add product, the system will tend to go to the reverse reaction and produce more reactant. Vice Versa. If more reactant is added, the system reacts to make more product to restore equilibrium.
What are 5 key words in a chemical change?
These are: reaction, chemical formula, reactant, product, chemical equation.
What effect does the concentration of reactants have on the rate of speed?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What is a product of substances that cease to change when equilibrium is reached?
concentration
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.
