Multiple Choice

which will produce more product?

• increasing temperature

• increasing surface area

• increasing mass/volume of reactants

• adding a catalyst

• increasing the pressure

Multiple Choice

which of these will DECREASE a rate of reaction

• adding a catalyst

• breaking it down in to a powder

• decreasing temperature

• increasing concentration of the solutions

Multiple Choice

what is an exothermic reaction?

• takes in energy

• gives out energy

Multiple Choice

which is an endothermic reaction?

• gets hotter

• gets colder

Multiple Choice

If i increase the temperature of an endothermic reaction....

• i will get more product

• i will get less product

Multiple Choice

if i increase the temperature of an exothermic reaction...

• i will get more product

• i will get less product

• they will stay at equilibrium

Multiple Choice

why does increasing pressure in the Harber process increase products? H2 +3H2  $$\Longrightarrow$$  2NH3 

• more reactants than products

• less reactants than products

Multiple Choice

The forward reaction of the Harber process is exothermic so to make more product i need...

• more heat

• less heat
