(A) Use information from Figure 22-17 to decide whether the nitrite anion, NO₂^–, disproportionates spontaneously in basic solution to NO₃^– and NO. Assume standard-state conditions.

(B) Does HNO₂ spontaneously disproportionate to NO₃^– and NO in acidic solution? Assume standard-state conditions. Use data from Figure 22-17.
