What is a gas?

In this state of matter, the molecules of carbon dioxide vibrate, rotate and translate.

100

What is endothermic?
A reaction which causes its environment to get colder?

100

What is average rate?
The difference in moles produced per unit of time

100

What is equilibrium?
A closed system's reversible reaction at constant temperature

100

What is a base?
It is a proton acceptor in the Bronsted Lowry theory

200

What is a diatomic gas?
Iodine, hydrogen, nitrogen, bromine, oxygen, chlorine, fluorine are examples of this atomic duo.

200

What is molar enthalpy?
The ratio between enthalpy change and the number of moles of a substance responsible for that amount of energy.

200

What is an inhibitor?
The factor involved in decreasing the rate when a cell wall component is impersonated by penicillin.

200

What is equal?
The relationship between forward and reverse rates for a reaction at equilibrium?

200

What is Ka?
DAILY DOUBLE (bet up to as much as you have) It takes both pH and the initial concentration in evaluating the true strength of an acid?

300

What is kinetic energy?
It is the 3/2 of the product between the gas constant and absolute temperature.

300

What is -5 kJ?
The delta H for B--> A, if B-->C + 3 kJ and A + 2 kJ -->C

300

What is two?
The number of activation complexes in a reaction profile with two hills.

300

What is neither?
The reaction that's favored when 2A(g)+B(s) =C(g) + D(g) is subjected to an increase in pressure.

300

What is infinite?
It is the value of Ka if a mole of HCl dissolves to produce a mole of H3O+

400

What is the size of molecules?
The volume of a gas' container is much larger than the total volume of these

400

What is 1?
The number of C=C bonds in C2H4.

400

What is effective?
The type of collision whose angle of attack is correct and the molecular impact is energetic enough.

400

What is an exponent?
DAILY DOUBLE! It's what the coefficient of a gaseous or aqueous molecule becomes in the equilibrium law expression?

400

What is 4?
It is the pH of a solution originally at pOH = 8 but which then becomes 100 X more acidic.

500

What is 20.0 L?
The final volume when 10.0 L of a gas at constant pressure is heated from 27 o C to 337oC?

500

What is 100.0 g?
The mass used in Q= mcDT when 2.050g of solid base are added to 100.00 ml of dilute aqueous acid

500

What is fast ones?
The reaction mechanism's steps whose time of reaction does not influence the rate expression.

500

What is increases?
It's what happens to the Keq when an exothermic equilibrium is cooled.

500

What is HSO4-?
The negative ion from H2SO4 appearing with H+ in the ice chart.
