The value of deltaH for the reaction CH3OH (l)---->CO (g) +2H2 (g) is +128.1 kJ? How many kJ of heat are consumed when 5.10 g of CO (g) is formed as shown in the equation
The vapor pressure of pure liquid A at 300K is 575torr and that of liquid B at 300K is 390torr. The molar volume of A is 0.0262L/mol and that of liquid B is 0.0306L/mol. Calculate the final partial pressures of A and B in the gas phase.
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
