If an equilibrium mixture is cooled what will be the effect on the intensity of the mixture color?
Cooling the equilibrium mixture will shift the equilibrium towards the side favoring the formation of the reactants (endothermic direction). The intensity of the mixture color could decrease if the reactants are colorless or have a lighter color compared to the products.
How do solids affect equilibrium in a chemical reaction?
Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.
What indicates a small equilibrium constant?
A small equilibrium constant (Kc) typically indicates that the reaction tends to favor the reactants at equilibrium rather than the products. This suggests that the reaction is not proceeding to a significant extent in the forward direction.
Why does a numerically large Keq mean that the products are favored in an equilibrium system?
A numerically large equilibrium constant (Keq) indicates that the equilibrium lies far to the right, with more products present at equilibrium than reactants. This means that the forward reaction is favored, leading to a higher concentration of products compared to reactants in the equilibrium state.
What direction doe the equilibrium shift when reactants are added to it?
Adding reactants to an equilibrium mixture will cause the equilibrium to shift to the right in order to consume the excess reactants. This helps restore the equilibrium conditions by favoring the forward reaction to produce more products.

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.
What will happen to the mixture at equilibrium if the temperature is decreased?
The system will rebalance.
Why should we cool the mixture in haber process?
To ensure that you have the more product which will be produced because the equilibrium will shift to produce it. This will produce heat and also more chemical product that you want in the equilibrium mixture.
What is a flash drum?
Vessels into which flow a mixture of liquid and vapor. The goal is to separate the vapor and liquid. For design calculations it is normally assumed that the vapor and liquid are in equilibrium with one another and that the vessel is adiabatic (no heat lost or gained). One must simultaneously satisfy a material balance, a heat balance, and equilibrium. In HYSYS/UniSim, this can be done using either a Separator or a Tank.
In a homogeneous mixture of particles are speeds even through out the mixture?
No. The particles have different speeds, and the average speed is used in calculations or discussions.
What will happen to the reaction mixture at equilibruim if the volume of the container is increased?
The equilibrium will be re-established.
How would the equilibrium concentration of H½O be affected by removing H½ from the mixture?
If you remove H½ from the mixture, the equilibrium will shift to the left to compensate for the loss, meaning more H½O will dissociate to reform some of the missing H½. This will increase the concentration of H½O in an attempt to restore equilibrium.
Does a mixture always have the same composition throughout an experiment?
No, a mixture can have varying compositions throughout an experiment depending on factors such as the components' solubility, temperature, and pressure. Mixing can lead to homogeneity or heterogeneity in the composition of the mixture.
A student found thet her mixture was 15 percent NH4cl 20 percent NaCl and 75 percent Sio2 Assuming her caculations are correct what did she most likely do incorrectly in her experiment?
The student most likely mistakenly swapped the percentages of NaCl and SiO2 in her calculations. She likely misinterpreted the data or made an error in transposing the numbers during the calculations.
