The decomposition of a certain ether was studied at 300 K and the data was plotted in a graph. The Y intercept equals 2.75 and the slope and the slope of the line is equal to -5. 0 X 10^ -3. Under these conditions, how long would it take for a sample to decompose to 25% of it original concentration?
