3 mole of Ag is heated from 300K to 1000K calculate `triangleH` when `P=1` atm and `C_(p)=23+0.01T`

For silver, C_p(JK^(-1)mol^(-1))=23+0.01T If the temperature (T) of 3 moles of silver is raised from 300 K to 1000 K at 1 atm pressure, the value of 'Delta H' will be close to

When two mole of an ideal gas (C​_(p.m.) = 5/2R) heated from 300K to 600K at constant volume. The change in entropy of gas will be :-

For an element, Cp = 23 + 0.01 T("JK"^(-1)"mol"^(-1)) . If temperature of 3 moles of that element is raised from 300 K to 1000 K at 1 atm pressure, the value of DeltaH will be ______ kJ.

One mole of diatomic gas is being heated in a closed tank 300K up to 1000K During the process part of the molecules dissociate At 1000K the energy of the diatomic molecules are only half of that of the whole gas By what factor has the gas pressure increased (P_(final)//P_(initial)) ? (The oscillation of the molecules are not to be taken in account)

When two moles of an ideal gas (C_(p.m.)=(5)/(2)R) heated form 300K to 600K at constant pressure, the change in entropy of gas (DeltaS) is:

Select the correct enthalpy at corresponding temperature using following datas (i) Heat capacity of solid from 0K to normal melting point 200K C_(p.m)(s)=0.035T" "JK^(-1)"mol"^(-1) (ii) Enthalpy of fusion =7.5 KJ"mol"^(-1) (iii) Enthalpy of vaporisation =30KJ "mol"^(-1) (iv) Heat capacity of liquid form 200K to normal boiling point 300K C_(p.m)(l)=60+0.016T " "JK^(-1)"mol"^(-1) (v) Heat capacity of gas from 300 K to 600 K at 1 atm C_(p.m)(g)=50.0" " JK^(-1)"mol"^(-1)

3 moles of an ideal gas is heated and compressed simultaneously from 300 K, 1 atm to 400 K, P atm. If change in entropy of gas is -3.3 cal//K then calculate value of P(in atm). C_(P)=(7R)/(2),R=2 cal//"mole"-K [In 2=0.7, In 3=1.1, In 5=1.6]

1 mole of CaCO_(3) is heated in a closed container fitted with a frictionless movable piston at 1 atm, 300 K. Calculate the magnitude of work obtained (in cal) [Use : R=2 "cal"//"K-mole"]
