Per the Haber process, increasing the pressure moves the equilibrium position to the right, increasing the yield.

What is the enthalpy change to burn 37.5 g of ammonia?
The enthalpy change to burn 37.5 g of ammonia (NH3) can be calculated using the standard enthalpy of formation of ammonia and the balanced chemical equation for its combustion. The enthalpy change will depend on the specific conditions of the reaction, such as temperature and pressure.
What three factors that can affect an equilibrium system?
A stress could be adding/taking away reactant/product. Or a change in temp and pressure (for gases). It depends on the system. Some of them get ulcers, but others just start drinking heavily. A system at equilbrium responds to a stress by shifting left or right (toward the reactants or toward the products) so as to minimize the effect of the disturbance. This is called LeChatelier's Principle. Some stresses can be a temperature change, a change in the concentration of one of the reactants or products, and a pressure change (if the reaction involves any reactants or products in the gaseous phase).
What is the standard test for ammonia gas?
Ammonia gas can be tested in these ways:1. It has a pungent smell2. It turns MOIST red litmus paper blue3. Test its alkalinity in water (pH ~ 11)4. It will extinguish a lighted splint5. It will easily dissolve in water
Does the cell potential change with concentration variations in a chemical reaction?
Yes, the cell potential can change with concentration variations in a chemical reaction. This is because the concentration of reactants and products can affect the flow of electrons in the cell, which in turn influences the cell potential.
Is ammonia a liquid?
Ammonia is a liquid at any temp,as long as it is in an contained vessel.The only change in ammonia, in a contained vessel ,is the internal pressure,due to the pressure-tempature relationship.Anhydrous ammonia is a 99.95% pure liquid for Refridgeration grade.Ammonium Hydroxide is cleaning solution grade,with ammonia only being 10-30% by volume.Out of a contained vessel,ammonia boils at -28 degrees and rapidly evaporates.
Can the concentration of the substance change if it is a gas?
Yes, the concentration of a gas can change due to factors such as temperature, pressure, and volume. These changes can affect the number of gas molecules in a given volume, thus altering the concentration of the gas.
What are things that decrease a reaction rate?
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
Why is high pressure necessary for making ammonia?
When producing ammonia, there is not a 100% change from reactants into products. In fact, around half of the reactants will change into ammonia, and then equilibria is reached and the amount of ammonia will stay the same. Increasing the pressure shifts the equilibria, so that more ammonia is produced when an equilibria is reached, making the process more efficient. Hypothetical example: 1 litre of reactants (normal pressure) -----> 0.5 litre reactants and 0.5 litre ammonia 1 litre of reactants (high pressure) -------> 0.2 litre reactants and 0.8 litre ammonia

3 conditions that will influence the direction a reaction will go?
change in concentration change in temperature change in pressure
Why can ammonia change a flower's color through a flower's pigment?
Ammonia increases the pH of the solution around the flower, which can alter the structure of the pigment molecules in the flower petals. This change in structure can affect the way the pigment molecules interact with light, leading to a shift in the flower's color.
How does ammonia affect the pH water?
Ammonia (NH₃) can increase the pH of water by acting as a weak base. When dissolved in water, it can accept protons (H⁺ ions) from the water, resulting in the formation of ammonium ions (NH₄⁺) and hydroxide ions (OH⁻). The release of hydroxide ions raises the pH, making the water more alkaline. The extent of this pH change depends on the concentration of ammonia and the buffering capacity of the water.
What change affect the turgor pressure of a potato cell?
you can soak it in a high concentration of salt water which causes it to lose its turgor pressure ,therefore it shrinks in size by diffusional water from inside the potato moves to the salt solution)
How does altitude affect phase change?
The change in pressure is highly affected by altitude.
What is osmotic change?
Osmotic change refers to the movement of water across a membrane in response to differences in solute concentration on either side of the membrane. This process is driven by osmosis, where water flows from an area of low solute concentration to an area of high solute concentration to equalize the concentration on both sides of the membrane. Osmotic changes can affect the volume and pressure of cells and organisms.
How is the effect on concentration change on the reaction rate seen in the rate law?
The exponents determine how much concentration changes affect the reaction rate
