What happens when the equilibrium constant is zero for a reaction?

If the equilibrium constant is zero, the reaction canNOT (will NEVER) reach equilibrium, it can not react back because all products are 'removed' (= concentration is zero).

Can a reaction have zero activation energy?
if a reaction is carried out at constant temperature to completion it will have a zero activation energy.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.
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.
When the actual free energy change of a reaction change in G has a numerical value of less than zero negative number what will happen?
When the delta G is negative the reaction is said to be spontaneous or in other words favorable. It also means the reaction is irreversible once full product concentration is reached. If delta G is positive, the reaction is unfavorable thus can easily be reversed. If it is zero it is at equilibrium.
If the equilibrium constant of a reaction is one what is the free charge?
Zero, if you mean what is the free energy change.
Can chemical equilibruim be zero?
No, the equilibrium constant might only become zero in the (irrational) situation when NO product(s) is (are) formed, thus when there is NO reaction AT ALL. This will only happen at zero Kelvin.
How is constant velocity and equilibrium related?
Constant velocity gives zero acceleration, force is mass times acceleration, thus if acceleration is zero then force is zero and equilibrium is zero force. Equilibrium = zero force :0=f=ma=mdv/dt = m0 when velocity is constant dV/dt=0.

The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
What is Motion without acceleration?
Such and object is said to be in equilibrium. No acceleration and no force.
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.
Why every action has reaction?
Every action has an equal and opposite reaction to achieve Equilibrium where the forces sum to zero.
What is the k in the rate law equation?
A rate constant
What happens when balanced forces acting on an object?
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
A body is in equilibrium when it's?
when it is at rest, or in constant uniform motion with net force and moment of zero (no acceleration)
If you slide a hockey puck across a frictionless ice rink these must be a horizontal force on it too keep it in the motion?
F=ma constant speed would mean 'a' acceleration is zero thus force zero. The puck would be in equilibrium, and the force would be zero at constant motion. Constant motion is constant velocity including the constant zero velocity.
