What are KC and KP and how they are related?
Kc and Kp are the equilibrium constants of gaseous mixtures. However, the difference between the two constants is that Kc is defined by molar concentrations, whereas Kp is defined by the partial pressures of the gasses inside a closed system.
How is the reaction quotient used to determine whether a system is at equilibrium?
Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.
How do you write equilibrium expressions in chemistry?
For gases, the equilibrium constant expression can be written as the ratio of the partial pressures of the products to the partial pressures of the reactants, each raised to a power matching its coefficient in the chemical equation.

What is the equilibrium law in chemistry?
The Law of Chemical Equilibrium
In a chemical system at equilibrium there is a constant ratio between. the concentration of products and the concentration of the reactants. This means that no matter what the starting composition of the reaction. mixture the ratio of reactants and products is a constant (Kc)
What is the equilibrium expression for the given reaction SrCO3 G <-- --> SRO’s co2 g?
For the reaction, SrCO3(s) =sro(s) +co2(g), the value of equilibrium constant Kp =2.2×10-4at 1002 k.
What is KC and KP equilibrium constant?
Kp And Kc are the equilibrium constant of an ideal gaseous mixture. Kp is equilibrium constant used when equilibrium concentrations are expressed in atmospheric pressure and Kc is equilibrium constant used when equilibrium concentrations are expressed in molarity. For many general chemical reactions aA + bB ⇋ cC + dD.
Which of the following equilibrium KC and KP are equal?
Kp only counts with gases molecule , while Kc only counts with aqueous solution+ gases. So here reactant and product both are gaseous that’s why only reaction having equal numbers of reactants and products will have kp=kc ie. change in number of moles is equal to 0. option(a) is correct.
What is Q and K in equilibrium?
Q is a quantity that changes as a reaction system approaches equilibrium. K is the numerical value of Q at the “end” of the reaction, when equilibrium is reached.

How do you write a reaction quotient?
We can calculate Q by writing out the equation using the balanced reaction and then using the given concentrations. If we compare Q to K, we can see that Q > K Q > K Q>KQ, is greater than, K.
What is the reaction quotient Q?
The reaction quotient (Q) measures the relative amounts of products and reactants present during a reaction at a particular point in time. The reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products.
