Explanation / Answer
1) we have to use the equation Kp = Kc (RT)n
2CH4= C2H2 + 3H2
n = total number of moles of products - total number of moles in reactants
= 3+1 -2
= 2
R = 0.08206, T = 273 + 1664 = 1937 K
plug in the values
Kp = 0.155 x ( 0.08206 x 1937 )2 = 3916.1072
second one also same but this time he has given Kp
plug the all values and get the answer
N2 + 3H2= 2NH3
n = 2-4 = -2, T = 273 + 254 = 527K, R is same
K = 2.80 x 10-3/ ( 0.08206 x 527 K)-2 = 12.7
K = 5.2365
