need not be..equilibrium constant is just a ratio of relative concentrations of products (multiplication of concentration in case of more than one products) to the concentration of reactants (multiplication of concentrations of reactants in case of more than one reactants)..the equilibrium concentration can be a very small number or can be a very number as well depending upon the relative concentrations of reactants and products..Unity equilibrium constants is just a special case which shows that the concentrations of products and reactants are equal..

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.
Why are chemical reactions that have equilibrium points close to completion preferable for manufacturing?
ans 1=when the rate of reverse reation become equals to rate of forward reaction,such chemical reation is in equilibrium
Which does newtons third law of motion state?
Newton's 3 laws of motion: 1. An object at rest will remain at rest, and an object in motion at a constant velocity will remain in motion at that constant velocity unless acted upon by and external, unbalanced force 2. Force equals mass times acceleration 3. Every action has an equal but opposite reaction
What is The order of reaction for which unit of rate and rate constant is same?
In a zero order overall process, the rate and rate constant will be the same. (Reaction order is an exponent, and if that exponent is "0" then the value is "1" and will cancel out.)
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
When a reaction system is at equilibrium the rates of the reaction in the forward and reverse directions are?
Equal to one another. K= k1/k-1 where k1 is the forward reaction, k-1 is the backwards reaction and K is the equilibrium constant.
In a reaction the equilibrium constant for the forward reaction is Kf and the equilibrium constant of the backward reaction is KB What is the relationship between Kf and KB?
Kb= 1/Kf (:
How can the magnitude of an equilibrium constant indicate the extent of a reaction?
The reaction proceeds to a very large extent if Kc >> 1. On the other hand, the reaction hardly proceeds if Kc << 1.
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.
If a eaction has an equilibrium constant just greater than 1 what type of reaction is it?
nothing
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
Find equilibrium constant of the reaction?
eqb constant k For a general EQN A+B=S+T the equilibrium constant can be defined by[1] k={S}{T}/{A}{B} {S} = MOLAR CONC. OF S{T} = MOLAR CONC. OF T{A} = MOLAR CONC. OF A{B} = MOLAR CONC. OF B
If a reaction system at equilibrium contains mostly product then?
k>>1
What do you need to know In order to write the equilibrium constant expression for a reaction?
To write the Keq for a reaction, the equilibrium concentrations of all reactants and products must be known. A specific example of this is how we define pH: the log of the equilibrium constant for any acid-base reaction. Just that simple, provided, of course, that the reaction does NOT go to 100% completion. Same principles apply to dissolution of partially soluble materials. If done correctly with consideration to chemical activity and coefficients, the so-called 'thermodynamic' equilibrium constants are obtained and are used in estimating quantities such as the entropy and enthalpy change of reaction. The more difficult ( and interesting part ) is how do we know what those concentrations are? Mass balance equations are a good place to start along with any stoichiometric considerations...easy to stick to 1:1 electrolytes and other simple reactions.
What are the conditions for equilibrium?
The two conditions of equilibrium are: 1. Concurrent Equilibrium the sum of vector forces through a point is zero. 2. Coplanar equilibrium, the sum of forces in a plane is zero and the sum of the torques around the axis of the plane is zero. These two conditions are similar to Ohms Laws in Electricity: Ohms Node Law the sum of the currents at a node is zero and Ohms Voltage law, the sum of the voltages around a loop is zero. These equilibrium conditions reflect the Quaternion mathematics that controls physics. Quaternions consist of a scalar or real number and three vector numbers. Equilibrium is the Homogeneous condition of a quaternion equation: the sum of the scalars or real numbers must be zero AND the sum of the vector numbers must also be zero. Thus there are TWO Conditions for Equilibrium. However if we were to use quaternions as nature does, then Equilibrium would be simplified to the zero quaternion condition.
What occurs when the forward and reverse reactions occur at the same rate?
If a forward and reverse reaction happen at the same rate, the result is called a dynamic equilibrium; the overall chemical composition does not change, even though reactions are constantly taking place.
Find any equilibrium solutions of the differential equation?
To find equilibrium solutions we set the differential equation equal to 0 and solve for y. so the equilibrium solutions are y = 0 and y = 1. is positive, which means the slopes on the slope field will be positive when y > 1.
