Final answer:
In order to find the boiling temperature of C3H4Br2 at a new pressure, we can use the Clausius-Clapeyron equation. To calculate the energy required to heat the sample of C3H4Br2, we can use the specific heat equation.
Step-by-step explanation:
In order to ascertain the boiling temperature of C3H4Br2 at a pressure of 540.0 mmHg, the Clausius-Clapeyron equation becomes instrumental.
The equation, ln(P2/P1) = -(ΔHvap/R)((1/T2) - (1/T1)), involves known values of pressure (P1) and temperature (T1), along with unknowns P2 and T2.
By rearranging the equation and solving for T2, the boiling temperature at the new pressure can be determined.
For the calculation of the energy required to elevate a 16.9-gram sample of C3H4Br2 from 97.5 °C to a gaseous state at 187.2 °C, the specific heat equation, q = mcΔT, proves valuable.
This involves computing the energy needed to raise the liquid to its boiling point, the energy needed for vaporization, and the energy required to heat the resulting gas to the final temperature.
Employing this approach facilitates a comprehensive understanding of the energy transformations involved in the heating process for the given substance
