At 760 K, Acetaldehyde Decomposes to Carbon Monoxide and Methane

Question 62

Multiple Choice

At 760 K, acetaldehyde decomposes to carbon monoxide and methane:
CH3CHO ⎯⎯→ CH4 + CO
A plot of ln [CH3CHO] versus time is linear. After 530 s, [CH3CHO] decreases to one half of its initial value of 0.10 M. What is the rate law for the reaction?
