Provide an example of a first-order process and describe how its half-life changes with temperature.

• A. A thermal decomposition that follows first order; as T increases, k increases and t1/2 decreases.
• B. A second-order reaction; t1/2 increases with temperature.
• C. A zero-order process; t1/2 constant with temperature.
• D. A first-order process; t1/2 increases with temperature.

Answer: (A)
