Are all solids sublimable? If no?Give an example.
(a) At high pressure of `A`, i.e., high concentration of `A`
(b)At low pressure of `A`, reaction reaction obeys first order kinetics
(c)The rate of reaction depends on both steps at all pressures.
(d)All of the above statements are correct.

Answer

A, C

Explanation

`(dP)/(dt) = k_(2)[A^(**)] = (k_(2)k_(1)[A]^(2))/(k_(-1)[A]+k_(2))`
At very high concentration of `A, A^(**)` will react with `A`. Therefore, `k_(-1) gt gt k_(2)`.
