Chapter 4: Problem 4

What is the difference between the following symbols in chemical equations: \(\longrightarrow\) and \(\rightleftharpoons ?\)

Short Answer

Expert verified
The symbol \( \longrightarrow \) represents a one-way or irreversible reaction, while the symbol \( \rightleftharpoons \) represents a reversible reaction, meaning the reaction can occur in both directions.

Step by step solution

01

Understanding Arrow Symbols

In chemical equations, arrow symbols are used to indicate the direction of a reaction. The arrows \( \longrightarrow \) and \( \rightleftharpoons \) both represent different types of chemical reactions.
02

Symbol \( \longrightarrow \)

The symbol \( \longrightarrow \) represents a one-way or irreversible reaction. In such reactions, the reactants are completely converted into products and the reaction can't return to the original state.
03

Symbol \( \rightleftharpoons \)

The symbol \( \rightleftharpoons \) represents a reversible reaction. In these reactions, the products can react to form the reactants. In other words, the reaction can occur in both directions simultaneously.
