**Unformatted text preview: **time of 22.8 min. The first thing necessary is to set up two expressions of the form of Equation (10.1), and then to solve simultaneously for the values of n and k . Rearrangement of Equation (10.1) and taking natural logarithms twice, leads to ln ln [ ] 1 1 - y = ln k + n ln t The two equations are thus ln ln [ ] 1 1 - 0.2 = ln k + n ln(13.1 min) ln ln [ ] 1 1 - 0.7 = ln k + n ln(29.1 min)...
