The molecular polarity and bond type of PCl3 is polar.
Answer: Conductor
Explanation: A material that conducts thermal energy well is called a thermal conductor.
Base on the problem given, it shows that the rate law for this reaction is directly proportional. The relationship between the reactants Z and Y that is proportional to the cube of [Z], it shows the concentrations of reactants is expressed by the rate law.
The model of the solar system is way smaller than the real object. The model of sub-atomic particles in a atom is way larger than the real object.
To answer this question, we will use the following equation:
<span>ln(P2/P1) = (∆Hvap/R)*((1/T1) - (1/T2))
</span>
Now we examine the givens of the problem and transform to standard units if required:
<span>∆Hvap = 30.5 kJ/mol
</span>R is a constant = <span>8.314 x 10^-3 kJ K^-1 mol^-1
T1 </span><span>= 91 celcius = 91 + 273= 364 Kelvin
</span>T2 = 20 celcius = 20 + 273 = 293 k3lvin
P1 is the standard atmospheric pressure = 760 mmHg
P2 is the value to be calculated
Substitute with these values in the equation:
ln(P2/760) = (30.5 / 8.314 x 10^-3) x ((1 / 364) - (1 / 293))
ln(P2/760) = - 2.4662 (Take the exponential both sides to eliminate the ln)
P2 / 760 = e^(-2.4462) = 0.0866
P2 = 0.0866 x 760 = 65.816 mmHg
