Question

For Chemistry legend class 11th...!

Answer 1

Answer:

a)

Explanation:

for diatomic gases we have to find gamma, by the relation

$\gamma = 1 + 2 \div n$

n = 3p - r

p - no of particles

r - independent relation between them

here for O2

n = 3 * 2 - 1

= 5

$\gamma = 7 \div 5$

we also know that

Cp = (gamma/ (gamma -1)) * R

putting the value of 7/5 we get

Cp = 7/2 R
