|---|---|---|---|---|---|
| Endothermic means? | adding energy
🗑
|
||||
| Adding energy results in what two things? | a change in temperature or a change in phase
🗑
|
||||
| At the triple point..? | All 3 phases exist
🗑
|
||||
| At the critical point...? | a critical pressure and a critical temperature exist
🗑
|
||||
| First Law of Thermodynamics | Energy is conserved, therefore the heat lost=the heat gained
🗑
|
||||
| Avagradro's Law | equal volumes of gases at the same temperature and pressure must contain equal numbers of particles
🗑
|
||||
| Volume is proportional to... | moles
🗑
|
||||
| 1 mole of any gas occupies how many liters at STP? | 224
🗑
|
||||
| Ideal Gas Law | Derived from Boyles and Charles Law
🗑
|
||||
| Equation for Ideal Gas Law | PV=nRT
🗑
|
||||
| The rate of reaction | defined as the change in concentration of the reactants per unit of time
🗑
|
||||
| factors that affect rate of reaction | effective cellision
🗑
|
||||
| effective cellision | orbitals must align correctly, must have sufficient energy (activation energy Ea)
🗑
|
||||
| Enthalpy | internal energy
🗑
|
||||
| Concentration | a change in concentration affects the total number of effective collisions
🗑
|
||||
| Surface Area | exposed to reaction. affects the number of effective collisions
🗑
|
||||
| Temperature | affects the activation energy, increase temp, increase energy of system, increase rate because more atoms have sufficient energy
🗑
|
||||
| Catalyst | increases the rate of reaction but it is not part of the reaction, lowers the Ea
🗑
|
||||
| Rinetic Molecular Theory | all atoms are in constand motion (knetic energy)
🗑
|
||||
| The degree of motion determines.. | the phase
🗑
|
||||
| gases have the highest... | knetic energy and the most entropy (measure of disorder)
🗑
|
||||
| Gases have the weakest.. | intermolecular forces
🗑
|
||||
| Knetic energy is zero at | 0 degrees Kelvin
🗑
|
||||
| Pressure | a force per unit of area
🗑
|
||||
| Stand Temperature | 0 degrees C and 273 degress K
🗑
|
||||
| Standard Pressure | 1atm = 760mHg = 101.3 kPa
🗑
|
||||
| At constant temperature and pressure, gas volume is | directly proportional to the number of moles of gas
🗑
|
||||
| Boyle's Law states that.. | the volume of gas varies inversely with pressure
🗑
|
||||
| When gas is compressed its temperature.. | increases
🗑
|
||||
| Charle's Law states that the volume of gas.. | is directly proportional to its temperature
🗑
|
||||
| Temperature and Volume are.. | directly proportional
🗑
|
||||
| Temperature and Pressure are... | directly proportional
🗑
