Which quantity is represented by the difference in energy between reactants and products on a reaction profile for an exothermic reaction?
If a reaction profile has products at a lower energy level than reactants, the reaction is:
When measuring the rate of gas production, why is it important to start timing as soon as reactants are mixed?
Which statement about reversible reactions at dynamic equilibrium is correct?
What is the effect of increasing the concentration of a reactant on a collision theory basis?
Which label on a reaction profile shows the minimum energy required for reactant particles to react?
For the reversible reaction A + B ? C + D at equilibrium, which statement is true?
Which observation would show that a reversible gas equilibrium has shifted to produce more product gas?
Which change would increase the extent of dissociation of a weak acid in water?
A student dissolves ammonium nitrate in water and observes the temperature decreases. This indicates the dissolution is:
