Aboiler is used to heat steam at a brewery to be used in various applications such as heating water to brew the beer and sanitizing the brewing tanks. 73.0% of the heat produced by the boiler is used to create saturated steam at 12.0 bars (absolute) from liquid water at 22' c. if 140 m3/h of steam is needed, what rate of heat does the boiler output?

  Q= m (h(p=10.0 bar,T= boiling temperature at p) - h( p,θ= 22°C)). The enthalpies are in J/Kg and are read from a steam table. Unfortunately I don't know the initial pressure at 22°C so I leave this work to you. 
m= ρ(12 bar, T) V with V= 0.73* 140 m³ /hr = 0.027 m³/s -> Q

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
