Unformatted text preview: vacuum. Also when you are trying to obtain the residual pressure if you do not open the valve before it is significantly larger than 0.60 torr you could ruin the glassware. 4. How would you determine the uncertainty in delta H o from a graph of ln K p verses 1/T? (see page A8) Because delta H o is defined by multiplying the gas constant times the negative slope of the graph we are going to have to use those values to determine the uncertainty. Since K p is related to pressures we would have to look at lowest increments that the capacitance manometer can read and the lowest increments the thermocouple can read....
