Which of the following is not a thermodynamic function?
Internal energy
Work done
Enthalpy
Entropy
Which of the following is intensive property?
Enthalpy
Entropy
Specific heat
Volume
C.
Specific heat
Intensive property in thermodynamics is independent of the amount of mass. Specific heat is an intensive property.
Extensive property in thermodynamics varies directly with mass. It includes enthalpy, entropy and volume.
For a first order gas phase reaction-
A(g) 2B(g) + C(g)
P0 be initial pressure of A and P, the total pressure at time 't'. Integrated rate equation is
Assertion : H2S is less acidic than H2Te.
Reason : Te has larger, radius than S.
