In titration, the piece of equipment that delivers a precise volume of solution into the flask

What is BURETTE

200

The number of Moles in 250 cm3 of 0.100mol/dm3 of NaOH

What is 0.0250 moles 

(0.100 x 00.250)

300

The moles of NaOH used in a titration lab with 25.0cm3 of 0.150 mol/dm3 NaOH. 

What is 0.00375mol

(0.150 x 0.025)

400

The number of moles of CH₃COOH in titration of 25.05cm³ of  NaOH with concentration of 0.150mol/dm³.

What is 0.00375 moles

500

The concentration in g/dm³ of 5.85g of NaCl (M_r=58.8) in 250cm³. 

What is 23.4g/dm³ (=5.85/0.250)

Reaction Rates/graps

100

On a graph of volume of gas vs time, this is the initial steepness of the slope

What is Rate of Reaction

200

On a graph where curve 1 reaches 60cm³ in 2 minutes and curve 2 reaches there in 4 minutes, this one has the fastest rate. 

What is Curve 1

300

Possible factors that cause the two different reactions on a graph to produce the same volume of product, but take different times

What are Different conditions (Temperature, Concentration, Pressure, Surface Area, Catalysts)

400

Reason why curve 3 levels off at 40cm³ and not 60cm³ like curve 1 and 2. 

What is Less reactant used 

500

When the Line of the reaction curve graph levels off. 

What is the end of the reaction

Industrial Processes

100

The catalyst used in the Haber Process to produce Ammonia 

What is Iron, Fe

200

The balanced equation of the Haber Process

What is N₂ + 3H₂ ->/<- 2NH₃

300

The typical temperature of the Contact Process

What is 450 degrees Celcius

400

In the Contact process yield is at 99% at 1atm, increasing pressure increases cost more than increasing the yield.  

Why is low pressure used in Contact process

500

The catalyst used in production of SO₃

What is Vanadium (v) Oxide (V₂O₅)

Energy & Catalysts

100

Meaning of E_a  on an energy profile diagram

What is  Activation Energy

200

Effect of a catalyst on the yield of a reaction

What is No effect- only increases reaction rate

300

This gives more particles energy > activation energy in a reaction

What is increasing Temperature

400

On an exothermic energy profile, products at lower energy than the reactants started with

What are products compared to reactants 

or 

What is - change of heat

or 

What is giving off energy to surrounding area

500

Ways catalysts can increase the Reaction Rate

What is 1. Lower activation energy 2. weaken bonds
