Q1.

Ethanol can be produced from ethene and steam.

 The equation for the reaction is: 

C2H4(g) + H2O(g) ⇌ C2H5OH(g) 

The forward reaction is exothermic. 

Explain how the conditions for this reaction should be chosen to produce ethanol as economically as possible. ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________

  1. Rate of reaction
    If the temperature is higher, the reaction is faster because particles move quicker and collide more often.

    If the pressure is higher (in gases), particles are closer together so they collide more often, increasing the rate.

    A catalyst can speed up the reaction because it lowers the activation energy, meaning particles need less energy to react.
