An exhaust gas control apparatus for an internal combustion engine is provided. The exhaust gas control apparatus is equipped with a NOx reduction catalyst, a reducing agent tank, a reducing agent supply device, a booster, a heater, and an electronic control unit. The electronic control unit is configured to perform control of raising a temperature of a reducing agent to a first target temperature such that the reducing agent supplied by the reducing agent supply device is brought into a gas-liquid mixed state in an exhaust passage, when energy of exhaust gas is lower than a first threshold.
