Which of the following liquids has the highest vapour pressure: acetone, methanol, water, ethyl, ether, or ethanol?. Put in order with highest to lowest. Please consider intermolecular forces in your reasoning.
A certain first-order reaction has a rate constant, k, equal to 2.1 x 10-5 at 355 K. If the activation energy for this reaction is 135 kJ/mol compute the value of the rate constant (s-1) at 550 K.
If the initial pressure of NH3(g) is 1.766 atm, calculate the % of NH3(g) left over after the reaction reaches equilibrium according to the balanced equation. The value of Kp at 600.0 °C is 455000.00. The initial pressure of the reaction products ..
