The enthalpy of formation of NH3(g) as per the following reaction is -46.11 kj/ mol at 298 K.
N2(g)+3H2(g)=2NH3(g)
Calculate the value of enthalpy of formation of NH3(g) at 100°C. The Cp0 (Jk-1mol-1) values are given as: N2(g)=29.12;H2(g)=28.82; NH3(g)=35.06• Assume the given heat capacity value to be temperature independent in the range.
For the equilibrium
2SO2(g)+O2(g)=2SO3(g) Kc=245(at100k)
The equilibrium concentrations are [SO2]=0.204M,[O2]=0.0264M and [SO3]=0.368M. Suppose that the concentration of SO2 is suddenly halved calculate Qc and use it to show that the forward reaction takes place to reach a new equilibrium.
A helium filled balloon at sea level has a volume of 2.1 L at 0.998 atm and 36℃. If it is released and rises to an elevation at which the pressure is 0.900 atm and the temperature is 28℃, what will be the new volume of the balloon?
An unopened, cold 2.00 L bottle of soda contains 46.0 mL of gas confined at a pressure of 1.30 atm at the temperature of 5.0℃. If the bottle is dropped into a lake and sinks to a depth at which the pressure is 1.52 atm and the temperature is 2.09℃, what will be the volume of gas in the bottle?
A sample of air in a syringe exerts a pressure on 1.02 atm at a temperature of 22.0℃ The syringe is placed in a boiling water bath at 100.0℃. The pressure of the air is increased to 1.23 atm by pushing the plunger in, which reduced the volume to 0.224 mL What was the original volume of the air?
