Stoichiometry The net heat evolved or absorbed in a chemical process, i.e. total change in the enthalpy of the system is independent of the State of aggregation & the state of combination at the beginning & the end of the reaction Number of intermediate chemical reactions involved Temperature & pressure None of these State of aggregation & the state of combination at the beginning & the end of the reaction Number of intermediate chemical reactions involved Temperature & pressure None of these ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Exert no attractive force on each other Collide without loss of energy Do work equal to loss in kinetic energy Are above the inversion temperature Exert no attractive force on each other Collide without loss of energy Do work equal to loss in kinetic energy Are above the inversion temperature ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The salt formed does not hydrolyse The strong base and strong acid reacts in aqueous solution The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case ANSWER DOWNLOAD EXAMIANS APP
