In which of the following reactions will kc = kp? in which of the following reactions will kc = kp?
(a) so3(g) + no(g) ↔ so2(g) + no2(g)
(b) 2 n2(g) + o2(g) ↔ 2 n2o(g)
(c) 4 nh3(g) + 3 o2(g) ↔ 2 n2(g) + 6 h2o(g)
(d) 2 so2(g) + o2(g) ↔ 2 so3(g)
(e) none of the above reactions have kc = kp.

Option A

Explanation:

Since we have a relationship between KC and KP as given below

KP=KC(RT)^dn

dn= difference in the no of gaseous products and Reactants

For A,dn= 1+1-(1+1)= 2-2=0

KP=KC(RT)^0

KP=kc(1) since a^0=1

Hence KP=KC

For B,dn=2-(2+1)=2-3=-1, hence KP not equal to KC

For C, dn=2+6-(4+3)=8-7=1

For D,dn=2-3=-1, KP is not equal to KC

So option A is correct answer

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

i think its 5049.

i hope this !
