A student dissolves ammonium nitrate in water and observes the temperature decreases. This indicates the dissolution is:
For the equilibrium N2(g) + 3H2(g) ? 2NH3(g) (exothermic), which change will increase the percentage yield of ammonia at equilibrium?
A graph of amount of product formed against time levels off to a horizontal line because:
How does increasing temperature increase the rate of a reaction?
What is the effect of increasing the concentration of a reactant on a collision theory basis?
Which quantity is represented by the difference in energy between reactants and products on a reaction profile for an exothermic reaction?
Which experimental variable directly affects the extent of reaction (how far reaction goes towards products) rather than just the rate?
When the temperature of an exothermic reversible reaction is increased, Le Chatelier’s principle predicts the equilibrium will:
When measuring the rate of gas production, why is it important to start timing as soon as reactants are mixed?
In a reversible reaction, adding an inert gas at constant volume will:
Adding a catalyst to a reaction usually:
