Equilibrium Flashcards
1
Q
The enthalpy change for a reaction is quite small. By reference to the number and type of bonds broken and made, explain how this might have been predicted.
A
- Similar types of bond broken and made
- Same number of the bonds broken and made
2
Q
State why there wouldn’t be any units in the expression for Kc
A
Units cancel as equal number of moles on each side of equation
3
Q
Dynamic equilibrium
A
- Forward and backward reactions proceeding at equal rate
- Conc of reactants and products remain constant
4
Q
Why isn’t there any units for K for this reaction:
A + 2B→ 3C
A
- Units cancel out
- As equal moles on both side
5
Q
A + 2B→ 3C exothermic
How will increasing the temp affect the time taken to reach equlibrium
A
- reduces the time
