Gce Model Questions Vol1 2019 Mathematics Question 3
Practice objective / multiple choice question 3 from the 2019 Gce Model Questions Vol1 Mathematics examination.
The time \(T\) (in minutes) required for a reaction varies directly as the square root of the concentration \(C\) (in mol\,L\(^{-1}\)) and inversely as the cube of the temperature difference \(\Delta\theta\) (in \(^{\circ}\)C) from a reference temperature. When \(C = 0.25\) mol L\(^{-1}\) and \(\Delta\theta = 5^{\circ}\)C, the reaction takes \(12\) minutes. Find the time required when \(C = 0.36\) mol L\(^{-1}\) and \(\Delta\theta = 3^{\circ}\)C. Give your answer as a fraction in simplest form.
