What will be the vapor pressure of Mono Chloro Benzene at 180 - 250 degree Celsius.

To determine the vapor pressure of Mono Chloro Benzene at different temperatures, we can refer to its vapor pressure-temperature relationship. This relationship can be obtained from experimental data or by using the Clausius-Clapeyron equation.

1. Experimental Data: We can consult vapor pressure data tables or databases, which provide the vapor pressure values of Mono Chloro Benzene at different temperatures. These tables are usually generated through experiments and can provide accurate values for a wide temperature range.

2. Clausius-Clapeyron Equation: If the experimental data is not available, we can use the Clausius-Clapeyron equation to estimate the vapor pressure at a desired temperature range. The equation is as follows:

ln(P2/P1) = (∆H_vap/R) * (1/T1 - 1/T2)

where:
P1 = vapor pressure at temperature T1
P2 = vapor pressure at temperature T2
∆H_vap = enthalpy of vaporization
R = gas constant
T1, T2 = initial and final temperatures, respectively

To use this equation, we need the enthalpy of vaporization (∆H_vap) and the initial vapor pressure at a known temperature (P1). It's important to note that these values are usually obtained from experimental data or from thermodynamic databases.

By substituting the known values into the equation, we can calculate the vapor pressure (P2) at the desired temperature (T2).

Please note that because I am an AI language model, I don't have access to an updated database or experimental values specific to Mono Chloro Benzene.
