Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
What generalizations about an equilibrium constant can be made if the value for K is large?
It will take a short time to reach equilibrium It will take a long time to reach equilibrium The equilibrium lies to the right The equilibrium lies to the left Two of these One of those answers...
What is a constant K formula?
K = constant
The reaction quotient Q indicates?
Q indicates wether or not a reaction will occur when the value of Q is compared to the equilibrium constant K if Q is larger than K the reaction will occur from product to reactant (decomposition) if Q is smaller than K the reaction will occur from reactant to product
How is the equilibrium constant of a reaction determined?
Molarity of products divided by reactants Keq=(products)/(reactants)
What is the difference between q and K in determining an equilibrium constant?
K is the equilibrium constant, Q is a concentration.
What does equilibrium and equilibrium mixture mean?
A quantity that characterizes the position of equilibrium for a reversible reaction; its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
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.
Does a large equilibrium constant mean that the reaction must be rapid?
NO!!! A large Equilibrium Constant means that nearly all the reactants have been used up to reach the equilibrium. Conversely a small K(eq) indicates that equilibrium is reached when very little of the reactants have been used.
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
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

What is the formula to find the spring constant?
F = - k x In this equation, x is the distance that the spring has been stretched or compressed away from its equilibrium position F is the restoring force exerted by the spring. k is the spring constant.
What is a constant K formula?
K = constant
What is constant k?
There are a number of K constants:1) k, the spring constant in Hooke's law relating deformation (strain) and force applied (stress) to a material body.2) k or kB, the Boltzmann constant, the physical constant relating energy and temperature at the particle level.3) K is a thermodynamic chemical equilibrium constant.4) Coulomb's constant k e is used in measuring electrostatic interaction between electrically charged particles. It comes from three other constants: the speed of light c 0 , magnetic permeability μ 0 , and electric permittivity ε 0.5) κ (kappa), in semiconductor manufacturing, means a low-κ dielectric: a material with a small dielectric constant relative to silicon dioxide.
Which of the following is the equilibrium constant of a reaction?
Keq = products/reactions
