What are the characteristics of a chemical system in equilibrium?
all the changes to a system cancel out APEX
When a reversible reaction is occurring in both directions at the same rate is called what?
When a reversible reaction is occurring in both directions at the same rate, it is called a dynamic equilibrium. In this state, the concentration of reactants and products remains constant over time, indicating that the forward and reverse reactions are happening at an equal rate.
When does space reach equilibrium?
When the rate of the forward reaction is the same rate of the reverse reaction.
Does an increase in pressure at constant temperature increase the rate constant of a reversible reaction in both directions?
The rate constant is unaffected, as demonstrated by Arrhenius equation: k = Ae^(-E/RT) where A is the pre-exponential factor (constant for a particular reaction) E is the activation energy R is the molar gas constant T is the thermodynamic temperature However, when pressure is increased at constant temperature for a gaseous reversible reaction, the concentrations of every reactant and product increase by the SAME factor. Since Kp (pressure equilibrium constant) is to remain constant, it means that the position of equilibrium will shift in such a way so as to decrease the total number of moles of gaseous species. Note: This answer can be improved by proving the last statement using a general example which, due to lack of time, I skipped. (Although some people might get the logic!!!)
In a reverse reactionproducts are formed from reactants and reactants are formed from products When they yield the same amount?
This indicates that the reaction has reached equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but both are still present in the system.
When a reversible reaction is occurring in both directions at the same rate?
The reaction is at dynamic equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant over time.

What describes a reaction that reaches equilibrium?
The product and reactants reach a final, unchanging level.
Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant
How is the molecularity of the rate-controlling step related to the overall reaction order?
The molecularity of the rate-controlling step may not necessarily be the same as the overall reaction order. The rate-controlling step is determined by the slowest step in a reaction mechanism, while the overall reaction order is the sum of the individual reactant concentrations in the rate law equation. It is possible for the molecularity of the rate-controlling step to influence the overall reaction order, but they are not always directly correlated.
When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
What does constant rate mean in math?
It means the same rate. Its going/moving at a constant rate.
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.
When a reversible reaction is occurring in both directions at the same rate is called what?
When a reversible reaction is occurring in both directions at the same rate, it is called a dynamic equilibrium. In this state, the concentration of reactants and products remains constant over time, indicating that the forward and reverse reactions are happening at an equal rate.
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
During dynamic equilibrium how do forward reaction rate and reverse reaction rate compare?
In dynamic equilibrium, the forward reaction rate (rate of reactant conversion to products) is equal to the reverse reaction rate (rate of reformed products converting back to reactants). This results in a constant concentration of reactants and products over time, signifying a balanced state where no net change in concentration occurs.
What equation shows how rate depends on concentrations of reactions?
The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.
