How does low pressure affect reaction?
Background: All reactions are equilibriums. This means that they react in both directions. Many cases this is to such a small extent that it is negligible.Answer: Increasing the pressure on a reaction will shift the reaction towards the side with the least number of moles of GAS.
When a reverse reaction is at its equalibrium what is its constant?
When a reverse reaction is at equilibrium, its equilibrium constant (K) is the reciprocal of the equilibrium constant for the forward reaction. This means that if the forward reaction has an equilibrium constant ( K_f ), the reverse reaction will have an equilibrium constant ( K_r = \frac{1}{K_f} ). Therefore, the value of the equilibrium constant for the reverse reaction reflects the ratio of the concentrations of reactants to products at equilibrium, but inverted.
What can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
You can calculate the equilibrium constant (Kc) of the reaction. This constant gives you information about the extent of the reaction at equilibrium and helps predict the direction in which a reaction will proceed.
What is the k in the rate law equation?
A rate constant
What does the equilibrium constant tell you?
The equilibrium constant can tell us how the reaction is going. If the constant is grater than one there are more products than reactants, so the reaction os closer to completion. If the equilibrium constant is less than 1 it shows that there are a lot more products than reactants so the reaction has not really started yet.

What is the rate constant for this first-order reaction?
The rate constant for a first-order reaction is a constant value that determines how quickly the reaction occurs. It is denoted by the symbol "k" and is specific to each reaction. The rate constant can be calculated by using experimental data from the reaction.
What is the rate constant for this zero-order reaction?
The rate constant for a zero-order reaction is a constant value that represents the rate at which the reaction proceeds, regardless of the concentration of reactants.
What is the value and unit of the rate constant for this reaction?
The value and unit of the rate constant for a reaction represent how fast the reaction occurs. The rate constant is typically denoted by the symbol "k" and its unit depends on the overall order of the reaction. The unit of the rate constant can be determined by the reaction rate equation.
What is the unit of the equilibrium constant in a chemical reaction?
The unit of the equilibrium constant in a chemical reaction is dimensionless.
Is a reaction with an equilibrium constant greater than 1 considered to be a spontaneous reaction?
A reaction with an equilibrium constant greater than 1 is considered to be a spontaneous reaction.
What is the relationship between the equilibrium constant and the rate constant in a chemical reaction?
The equilibrium constant (K) and the rate constant (k) in a chemical reaction are related but represent different aspects of the reaction. The equilibrium constant describes the ratio of products to reactants at equilibrium, while the rate constant determines the speed at which the reaction occurs. The two constants are not directly proportional to each other, as they represent different properties of the reaction.
What is the relationship between the rate constant of a reaction and the activation energy of the reaction?
The rate constant of a reaction is directly related to the activation energy of the reaction. A higher activation energy typically results in a lower rate constant, meaning the reaction proceeds more slowly. Conversely, a lower activation energy usually leads to a higher rate constant, indicating a faster reaction.
What are the units of the equilibrium constant K in a chemical reaction?
The units of the equilibrium constant K in a chemical reaction are dimensionless.
What are the units of the equilibrium constant in a chemical reaction?
The units of the equilibrium constant in a chemical reaction are dimensionless, meaning they have no units.
Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
When does q equal delta h in a chemical reaction?
Q equals delta H in a chemical reaction when the reaction is at constant pressure and the temperature remains constant.
