Stoichiometry & Net Ionic
What is the molar mass?
Chemical changes involve this.
What is the breaking and forming of bonds?
Rate laws can only be found through this.
What is experimentally?
The taller the activation energy hill in an energy profile diagram means the reaction will be this.
What is slower?
The mole ratio that converts one substance into another is found from this.
What is the balanced chemical equation?
Acid-Base reactions involve the transfer of this.
What is the H+ ion (or proton) ?
For a First Order reaction, when the initial concentration of a reactant is doubled, this causes the rate to do this.
What is double?
Reaction intermediates in a reaction mechanism are this and then this.
What is made and then used up?
When writing a Net Ionic equation, this state(s) of matter are split into their constituent ions.
What are aqueous compounds?
Redox reactions involve the transfer of this.
What are electrons?
When given a graph of Ln[A] vs time that has a straight line, this implies this kind of rate law.
What is First Order?
When a substance is added to a reaction to make it go faster, it is called this AND works by doing this.
What are catalysts and by decreasing the activation energy?
These ions are always soluble.
What are NH4+, K+, Na+, and NO3- ?
OIL RIG and LEO the lion says GER are two mnemonics for remembering redox reactions. These stand for this.
(you can do either one)
What is
OIL RIG = Oxidation is Loss, Reduction is Gain
LEO GER = Lose electrons Oxidation, Gain Electrons Reduction ?
Elementary reaction rate laws can be determined from this.
What is the balanced chemical equation?
These three things need to occur for a reaction to happen.
What are particles colliding, collisions have enough energy to overcome the activation energy, and a collision has the correct orientation?
This is the net ionic equation for strong acid-base reactions.
What is H+ + OH- --> H2O ?
What is chemical because ionic bonds are being broken and new ion-dipole forces are being formed between the ions and water and physical because mixing water and a salt does not change the identity of either substance?
Steady State Approximation must be used for solving the overall rate law of a reaction mechanism when the slow step is this.
What is not the first step?
These are other ways to speed up a reaction besides adding a catalyst.
What are increasing reactant concentrations, increasing surface area, increasing the pressure of gases, and increasing the temperature?
