General Chemistry
An organic compound undergoes first order decomposition. The time taken for its decomposition to \(\frac{1}{8}\text{th}\) and \(\frac{1}{10}\text{th}\) of its initial concentration are \(t_{1/8}\) and \(t_{1/10}\) respectively. The value of \(\left[ \frac{t_{1/8}}{t_{1/10}} \right]\) is [Given \(\log_{10} 2 = 0.3\)]
