Stoichiometry In case of a solution (not of a solid in a liquid), whose total volume is less than the sum of the volumes of its components in their pure states, solubility is Independent of temperature Increased with decrease in pressure Increases with rise in pressure Unchanged with pressure changes Independent of temperature Increased with decrease in pressure Increases with rise in pressure Unchanged with pressure changes ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to 1335 1225 1525 1735 1335 1225 1525 1735 ANSWER DOWNLOAD EXAMIANS APP
