Which is the correct expression for the h-atom balance for the reaction below occurring at steady state with a feed flow rate of 100 mol/s that is equimolar ch4 (a) and o2 (b)? ch4 + o2hcho + h20 assume that the conversion of reaction is 100%. select one: o a. 50 mol/s = 2nhcho + 2nh20 - 4nch4 o b. 50 mol/s = 4nch4 + nhcho + 2nh20 o c. 200 mol/s = 2nch4 + nhcho + 3nh20 o d. 200 mol/s = 2nhcho + 2nh20 o e. not enough information is given

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
