What does the double (backwards-forwards) arrow mean?

Question

in a limiting reactant problem? do i treat it like a regular arrow? or does it have any effect on the answer?

In a Limiting reactant problem, does it make a difference if the arrow is like that? would it change the outcome? or do i ignore it?

DOES IT AFFECT THE OUTCOME OF A LIMITING REACTANT PROBLEM???????????

thanks guys
does it change the answer in a limiting reactant problem? or can i just solve it as if it were a regular limiting reactant problem?

Answer 1

the double (backward-forward) arrow in a limiting reactant problem just simply means that the reaction is incomplete.

NOT ALL reactants has reacted. this is due to the fact that a weak acid or base is used as the reactant and thus, results in the
product not completely formed.

the double arrow can also mean that the reaction is reversible. this applies for esterification and acid hydrolysis reactions. they are reversible.

hope this info helped. :)

Answer 2

Solve it as a regular L.R. problem. Just know that the double arrow means that there is an equilibrium in that reaction. There is just as much reactants as there is products. You can then use catalysts or temperature to help force the reaction to either mostly all products or mostly all reactants.

Answer 3

It means the reaction can go both ways, depending on the lenght of the second arrow for how much. Using the ICE method, you will be able to run the reaction back and forth, in principal.

Answer 4

I thought it meant that the reaction could go either direction.

Answer 5

Equilibrium. It could go back the other way, as well as, forward.

Answer 6

If you mean << or >> it usually means way less than or way greater than.
