56. Solution to Chemistry Problem

2. Diazonium salt decomposes according to the equation CH3C6H4N2Cl+H2O=CH3C6H4OH+N2+HCl. The decomposition process is a first-order reaction. The reaction rate constant at 297.9 K and 308.2 K is 2.5*10-4 s-1 and 3.2*10-4 s-1, respectively. Determine the time during which 99% of the diazonium salt decomposes at a temperature of 315 K.
