What should be done to increase the rate of chemical reaction between solid and gaseous substances?

In order to increase the rate of any reaction, there are several ways. The first is to increase the temperature of the ongoing reaction. As the temperature rises, many substances begin to change their chemical and physical properties, this allows substances to react more quickly.

The second way is to increase the area of the reaction, so the substances will react faster.

And the third way is to introduce a catalyst into the reaction, under the influence of which the reaction will proceed at a higher rate.
