C2H4(g) + H2(g) mc009-1.jpg C2H6(g) + 137 kJ What happens to the amount of ethane (C2H6) when the temperature of the system is i
ncreased? The amount of ethane decreases. The amount of ethane increases initially and then decreases. The amount of ethane increases. The amount of ethane decreases initially and then increases.
Answer is: t<span>he amount of ethane decreases. This reaction is exothermic, which means that heat is released. According to Le </span>Chatelier's principle w<span>hen the reaction is </span>exothermic heat is included as a product and when <span>the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the left, producing less ethane.</span>
