How does the reaction rate depend on temperature? At what temperature, 20 ° C or 40 ° C, the reaction will proceed with a higher speed?

How does the reaction rate depend on temperature? At what temperature, 20 ° C or 40 ° C, the reaction will proceed with a higher speed? Why are many chemical reactions in industry carried out at elevated temperatures?

When the temperature rises for every 10 ° C, the reaction rate increases by 2-4 times. At 40 ° C, the reaction will proceed faster than at 20 ° C, because the reaction rate increases with increasing temperature.
In industry, many reactions are carried out at elevated temperatures in order to increase the reaction rate. And many reactions at low temperatures do not go at all or go, but too slowly.
