A mixture of CH4 and C2H6 (both are gases) has a total pressure of 0.53 atm. Just enough O2 is added to the mixture to bring about complete combustion of each reactant to gaseous products. The total pressure of the product gases is 2.2 atm. Assuming constant volume and temperature, find the mole fraction of CH4 in the mixture.

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.
