Question

Нужно выразить 1/T2.

Answer 1

Выражение T1:

$\frac{P_{2}}{P_{1}} = \frac{\Delta H}{R} ( \frac{1}{T_{1}} - \frac{1}{T_{2}} ) \\ \frac{P_{2}}{P_{1}} \frac{R}{\Delta H} = ( \frac{1}{T_{1}} - \frac{1}{T_{2}} ) \\ \frac{P_{2}R}{P_{1}\Delta H} + \frac{1}{T_{2}} = \frac{1}{T_{1}} \\ \frac{1}{T_{1}} = \frac{P_{2}RT_{1} + P_{1}\Delta H}{P_{1}\Delta HT_{2}} \\ T_{1} = \frac{P_{1}\Delta HT_{2}}{P_{2}RT_{1} + P_{1}\Delta H}$
