The Boltzmann distribution curve for a gaseous mixture of ethene and hydrogen is shown. Nickel is an effective catalyst for the reaction that occurs. How would the diagram be different if the same reaction mixture were at a higher temperature?
- AThe curve is unchanged.
- BThe values of both $E_a$ (catalysed) and $E_a$ decrease.
- CThe values of both $E_a$ (catalysed) and $E_a$ increase.
- DThe values of both $E_a$ (catalysed) and $E_a$ remain the same.
