Question 17

Methanoic acid and propanol react to form propyl methanoate and water.

methanoic acid + propanol ⇌ \rightleftharpoons\,⇌ propyl methanoate + water

A chemist warms a mixture of pure propyl methanoate and water in a sealed flask.

What happens to the propyl methanoate and water in the flask?

[1]
A

Only the propyl methanoate breaks down, and the water is unchanged

B

The water evaporates and separates from the propyl methanoate

C

They cannot react, because they are on the right of the equation

D

They react together to form methanoic acid and propanol
