Revision "Reversible Reactions and Dynamic Equilibria

Question 1

What does a reversible reaction mean?

Answer 1

= products can convert back to the reactants
= double arrow- reach equaliberoam

Question 2

What happens in a closed system?

Answer 2

= no atoms can enter or leave the system

Question 3

What is an equalibrian?

Answer 3

= forward and backwards reaction have not stopped, taking place at the same rate
= concentration is constant
=
= dynamic

Question 4

industrially what does higher temperature give?

Answer 4

= low temperatures give higher yield of product but has lower rate of reactions
= comprimises are used

Question 5

Industrial and pressure?

Answer 5

= higher pressures give higher yield and faster rate
= expensive to produce
= equipment used is expensive

Question 6

What is the effect of catalysts ?

Answer 6

= no effect on position of equalirbain
= speed up rate in which equalibrian is reached- speeds up forwads and backwards reaction by the same amount
