Question

Predict which of the following would shift the equilibrium to the right in the following reaction

C2H2 + H20---> CH3CHO
<---
1)removing H2O (g) from the system
2)adding CH3CHO (g) to the system
3) removing C2H2 (g) from the system
4) adding H2O (g) to the system

Answer 1

if you think of the reaction arrow to be the pivot-point on a balance, when you change something about a system at equilibrium, the balance is "broken". for each of those changes, which one will force the movement from the reactant side to the product side?

Answer 2

removing C2H2 ?

Answer 3

if you remove \(C_2H_2\), then the reactant side now "weighs less" than the product side. Will that make some of the mass move to the right to restore the balance?

Answer 4

no it wont

Answer 5

so what change (stress) will cause the reaction to shift and move some of the mass from the left side to the right side?

Answer 6

you need to make the reactant side "too heavy" or the product side "too light"

Answer 7

adding H2O

Answer 8

that will do it, GJ

Answer 9

Thanks :)
