IB Chemistry HL IA Example 1 (23/24)
$20.00Price
This Chemistry HL IA scored 23/24 (Grade 7) and was created by a 45/45 student for the November 2024 session.
Research Question: What is the effect of temperature (298.0 K, 303.0 K, 308.0 K, 313.0 K, 318.0 K, 323.0 K) on the rate constant (s⁻¹) of the decomposition of hydrogen peroxide catalysed by magnesium (IV) oxide, by measuring the time taken (s) for the evolution of 30 cm³ of oxygen gas in a gas syringe?
This resource is a brilliant exemplar of the Chemistry HL Internal Assessment and can be used as a model for both the structure and the level of investigation and analysis required to achieve a strong Grade 7 in the task.
