Consider the following equation in chemical equilibrium. C2H4(g) H2(g) C2H6(g) 137 kJ What happens to the amount of ethane (C2H6) when the temperature of the system is increased

Respuesta :

The amount of ethane decreases

increasing the temperature (adding energy), will drive the reaction to the left

What happens to the amount of ethane (C2H6) when the temperature of the system is increased ?

C2H4(g) <--> C2H6(g) + 137 kJ

because this reaction is an exothermic reaction and the heat is a product of this reaction, So when the number of temperature increases

  • so (more heat will be added) so the reaction will go leftward (toward reactants ) so the amount of C2H4 & H2 will increase and the amount of ethane C2H6 will decrease.
