Well, the most famous example is the Haber Process. Normally the equation is
N+3H<->NH3. The problem is that it is exothermic, and the more ammonia you make the hotter it gets. If you stress the equation to the right by increasing pressure. Fritz Haber perfected this process although it took a while to get it right, as he basically had very hot and very pressurized cookers for making ammonia. This was great for helping feed the world but this actually happened in 1914 during WWI. Fritz Haber used it to make cheap gunpowder and explosives for Germany as they were under allied blockade. His wife hated him so much for that, that she killed herself. He also created the chlorine gas warfare. Nice guy.

How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
What effects does the concentration of reactions have on the rate of a reaction?
increasing the concentration increases the rate of the reaction
Substance that increases rate of chemical reactions?
catalyst
How do enzymes regulate the rate of chemical reactions?
Enzymes serve to speed up reactions by lowering the energy of activation
When the wage rate paid to labor is below equilibrium?
When the wage rate paid to labour is below equilibrium wage, then labour is undersupplied. As firms require more labour to maximise their profit, they will slowly raise their wage rate (because revenue from labour > costs) until the equilibrium level is achieved (since no more profit is achieveable at this level).
How can you maximise the rate of energy transfer to keep things cool?
you can maximise the rate of energy transfer by using materials that; -are good conductors -are painted Matt black -have the air flow around them maximised
How can we maximise the rate of energy transfer to keep things cool?
we dont.
How do you find the tax rate if you have the pre tax and after tax profit?
After Tax Profit = Pretax Profit * (1 - Tax Rate) Solve for Tax Rate Tax Rate = 1 - (After Tax Profit/Pretax Profit)
Is speed the rate of change?
NO! It is the rate of reactions!
How particle collisions that affect the rate of chemical reactions?
When the number of particle collisions increase the rate of chemical reactions also increase.
Do enzymes decrease the rate of chemical reactions?
No, they Increase the speed of chemical reactions
Equilibrium is achieved when the and chemical reactions continue to take place at the same rate?
Equilibrium occurs when the forward and backward reactions happen at the same rate
What are the 5 factors that can affect the rate of chemical reactions?
5 factors that can affect the rate of chemical reactions are temperature, pressure, concentration, stirring, catalysts.
In finance what is rate of return?
In finance, the rate of return is a profit from an investment whereas the set rate determines the profit. For example, if an investor receives 10% for every $100 invested then the rate of return would be $10.00.
Do you want Gross profit rate high or low?
Higher gross profit indicates high profit margins which is good!
How the difference in the movement of atoms at two different temperatures affects the rate of most chemical reactions?
Generally at high temperature the rate of chemical reactions is greater.
