One mole of an ideal gas is initially at 0o C and 1 atm pressure. If it absorbs 1000 cal heat during a reversible isothermal expansion, what will be its final volume?
102.5L
242.5L
22.4L
121.25L
The temperature of the system decreases in an
adiabatic compression
isothermal compression
isothermal expansion
adiabatic expansion
For exothermic reaction
Hr = Hp
Hr > Hp
Hp >Hr
All of these
For an endothermic reaction, energy of activation is Ea and enthalpy of the reaction is ΔH (both of these in KJ/mol). Minimum value of Ea will be
equal to zero
less than ΔH
equal to ΔH
more than ΔH
