# The decomposition of a solid metal carbonate is represented by the equation below.

\[ \text{MCO}_3\text{(s)} \rightleftharpoons \text{MO(s)} + \text{CO}_2\text{(g)} \]

For this reaction, \(\Delta H^\circ = +120\text{ kJ/mol}_{\text{rxn}}\) and \(\Delta S^\circ = +200\text{ J/(mol}_{\text{rxn}}\cdot\text{K)}\). Assuming that \(\Delta H^\circ\) and \(\Delta S^\circ\) are constant over the given temperature range, under standard conditions, the forward reaction is thermodynamically favored at which of the following temperature ranges?
