Verkhoyansk, a small Russian village, experiences the coldest winter nights on earth (-50 °C on average). The town uses mercury vapor lamps (HVLS) as a light source. During these winter nights, mercury in the lamps freezes. How much energy (in ) is required to heat the frozen mercury to the operating temperature of HVLS (800 °C) on the average winter night? Note: HVLs contain 0.737 ml Hg. Use the following data for mercury. AH (in kJ mol-?): A Hus = 2.33 AHvap = 59.2 c (in Jg-1 °C-): Csolid = 0.140 Cliquid = 0.149 Ceas = 0.007 Other data: Ti = -38.9°C To = 357 °C dyg = 13.6 g ml-1 A. 3713.7 B. 3407.4 C. 3.7 D. 3871.4 E. 1851.5 14. The vapor pressure of pure water is 25 °C is 23.8 torr.

A. 23.4 B. 24.3 C. 0.451 D. 0.443 E. 23.8

Answer 1

To find rate, the formula is Rate = k [ClO2]^x * [OH-]^y

where k = Rate constant
