Gce Model Questions Vol1 2025 Mathematics Question 41
Practice objective / multiple choice question 41 from the 2025 Gce Model Questions Vol1 Mathematics examination.
The time \(T\) (in minutes) taken for a chemical reaction varies directly as the square of the concentration \(C\) (mol L\(^{-1}\)) and inversely as the temperature difference \(\Delta T\) (°C) from ambient. When \(C = 0.5\) mol L\(^{-1}\) and \(\Delta T = 20\) °C, the reaction takes 8 minutes. Find the temperature difference required for the reaction to take 5 minutes when the concentration is \(0.8\) mol L\(^{-1}\).
