The mass expression for the system is K= (aH₂)² × aO₂ / (aH₂O)² = 5.31× 10⁻¹⁰.
we may derive mass action expression out from equation above,
K= (aH₂)² × aO₂ / (aH₂O)² = 5.31× 10⁻¹⁰.
what is mass action expression ?
An equation that compares the product activities increased towards the power of its coefficients to the reactant activity increased to the power of its coefficients is known as the mass action expression.
- As much that you have a balanced equation to use as a guide, it is fairly simple to construct the expression correctly. So let's think about the subsequent generic aqueous solution reaction.
- The coefficient for that species is represented by each of the lowercase letters.
- The reaction quotient / concentration fraction are other names for the mass-action expression.
- The letter Q stands for mass-action expression (also known as reaction quotient or concentration fraction).
