Why rate of a reaction increase when temperature increases?

The rate of a reaction gets doubted when temperature increases from 27°C to 37°C. By what factor will it change for the temperature range 17°C to 27°C

Why rate of reaction increases when concentration increases ?

Why rate of reaction increases when surface area increases ?

Some features of a reversible reaction are given below: Product formation increase when the temperature is increased. Explain the reason for above inference.

The large increase in rate of a reaction on rise temperature is due to

By increasing the temperature by 10°C, the rate of forward reaction at equilibrium is increased by a factor of 2. The rate of backward reaction by this increase in temperature

The rate of which reaction increases when the concentration of nitrogen is increased in the manufacture of Ammonia? Forward reaction/Back ward reaction.
