In a chemical reaction device that improves a yield of a product and that causes a reaction, progress of which in a gaseous phase is restricted by a chemical equilibrium between a source material and the product, a cumulative value is not less than 500 mm, the cumulative value being obtained by cumulatively adding, from one end to the other end of a cooling surface in a height direction, products of (i) a distance L between (a) a surface of a catalyst layer which surface is in contact with a transmission wall and (b) an outer surface of the cooling surface and (ii) a height H of the catalyst layer corresponding to the outer surface having the distance L.

This lithium-containing transition metal composite oxide includes secondary particles that are aggregates of primary particles into or from which lithium ions are dopable or dedopable, and satisfies the following conditions:

Lithium-containing transition metal composite oxide, positive electrode active material for lithium secondary battery, positive electrode for lithium secondary battery, lithium secondary battery, and method for manufacturing lithium-containing transition metal composite oxide

A source material gas () is supplied to a catalyst (), a first heating medium () is caused to flow through a first heat exchange section () so that a temperature of a surface of the first heat exchange section () on a catalyst side is maintained higher than a dew point of a reacted gas (), a second heating medium () is caused to flow through a second heat exchange section () so that a temperature of a surface of the second heat exchange section () on a space () side is maintained not higher than the dew point of the reacted gas (), and a liquid obtained by condensation in the space () is allowed to fall down so as to be separated from the source material gas.
