Indicate whether the statement is true or false
Assuming the liquid is an ideal solution, determine the bubble point pressure, and determine whether the first bubble of vapor contains more product (C+D) or more reactant (A+B).
A reaction A+B?C+D occurs in the liquid phase. A vessel contains a liquid at P=0.5 MPa and T=298.15 K. The vessel initially contains 10 moles of A and 10 moles of B, but the reaction is allowed to reach equilibrium at P=0.5 MPa and T=298.15 K. After the reaction reaches equilibrium, the pressure is reduced isothermally until the first bubble of vapor forms. The equilibrium constant for the reaction is 0.8. Vapor pressures are 0.120MPa for compound A, 80kPa for compound B, 0.150MPa for compound C and 70kPa for compound D.
Technician Asays a wheel-mounted pressure sensor uses wireless communication to send the pressure signal to a PSB computer, which in turn, illuminates the warning light or icon in the dash. Technician B says factory sensors are usually installed in place of the regular tire valve stem. Who is correct?
A. A only B. B only C. Both A and B D. Neither A nor B
