Solution
This seems like a series of questions from a chemistry quiz. Here are the answers:
-
The symbol used to represent a reversible reaction is ⇌.
-
In a reversible reaction, if the forward reaction is endothermic, the reverse reaction is exothermic.
-
If a chemical reaction happens in a container from which none of the reactants or products can escape, this is a closed system.
-
The production of ammonia from nitrogen and hydrogen is described by the reversible equation N2 + 3H2 ⇌ 2NH3. At equilibrium, nitrogen, hydrogen, and ammonia will be present.
-
When a reversible reaction reaches equilibrium, the statement that is not true is "The concentrations of all reactants and products are equal".
