3 mole of hydrogen is mixed with 1 mole of neon. The molar specific heat at constant pressure is

Options

  1. A9R4\frac{9 R}{4}
  2. B9R2\frac{9 R}{2}
  3. C13R4\frac{13 R}{4}
  4. D13R2\frac{13 R}{2}

Correct answer

C. 13R4\frac{13 R}{4}

Step-by-step solution

For mixture, CV=n1CV1+n2CV2n1+n2C_V=\frac{n_1 C_{V_1}+n_2 C_{V_2}}{n_1+n_2} =3×52R+1×32R3+1=9R4=\frac{3 \times \frac{5}{2} R+1 \times \frac{3}{2} R}{3+1}=\frac{9 R}{4} CP=CV+R=9R4+R=13R4C_P=C_V+R=\frac{9 R}{4}+R=\frac{13 R}{4}
