Question

In the Reaction, Initial, Change, Equilibrium (RICE) table started for calculating equilibrium concentrations of the reaction shown, the terms in the "change" row are ________
M²⁺ + 4L

\leftrightarrows

ML₄²⁺

\begin{array} { l l c c c } \mathbf { R } & { \left[ \mathbf { M } ^ { 2 + } \right] } & { [ \mathbf { L } ] } & { \left[ \mathbf { M L } _ { 4 ^ { 2 + } } \right] } \\\text { I } & 0.10 M & 0.32 M & 0 M \\\text { C } & & & \\\text { E } & & &\end{array}

The stoichiometry of the reaction dictates that for every 1 mole of M²⁺ that reacts, 4 moles of L react, and 1 mole of ML₄²⁺ is formed. Hence, the changes are -x for M²⁺, -4x for L, and +x for ML₄²⁺.
