Answers : (1)



By just visualising the option you can say that answer must be greater than 30 so option 4 is correct.



As efficiency is 85% so we have

0.85moles of Z is formed by 2 moles of X

=> 15 moles of Z is formed by

2*15/0.85 moles of X = 35.3 moles of X

So 4th option is correct

The molar volumes of ice and water are 0.0196 and 0.0180 litres per mole at 273K. If ΔH for the transition of ice to water is 1440 calories per mole at 1 atm pressure, find ΔU.
From eqn. ΔU + Δ(PV) ΔH = = ΔU + ΔPV + PΔV Given, 1440 = ΔU + 0.0196*273 + 0.0180*273 ΔU = 1440 – 10.2648 = 1429.73 calories.
