Question

For the reaction PCI; (g)+ Cl2(g) = PCI; (g) at 250°C,
the value of K. is 26, then the value of K, on the same
temperature will be
(a) 0.61
(b) 0.57
(c) 0.83
(d) 0.46
.​

Answer 1

Answer:

0.61

Explanation:

ANSWER

K

p

=K

c

×(RT)

Δn

Δn= no of moles of gaseous produt - number of moles of gaseous rectant

therefore Δn=1−2=−1

R = 0.0821, T = 250 + 273.15 = 523.15 and K

c

= 26

soK

p

=K

c

×(RT)

−1

K

p

=

0.0821×523.15

26

=0.61
