The leathery pad helps the camel because it prevents the camels feet from sinking into the sand.
Equilibrium chemical reaction between chair and boat forms is:
Kc =
Suppose the total number of molecules is x
Number of molecules of chair form is 6.42/100 x
Number of molecules of boat form is 93.58/100 x
Kc =
= 14.6
