Mention whether the increasing pressure will cause the reaction to go into forward or backward direction, using (b) for backward, (f) for forward, (n) for no change by selecting any of the choices given for the following reactions respectively (i) COCl 2 g ⇌ CO(g) + Cl 2 (g) (ii) CH 4 (g) + 2S 2 (g) ⇌ CS 2 (g) + 2H 2 S(g) (iii) CO 2 (g) + C(s) ⇌ 2CO(g) (iv) 2H 2 (g) + CO(g) ⇌ CH 3 OH(g) (v) CaCO 3 (s) ⇌ CaO(s) + CO 2

Step-by-step solution

(i) n p > n r , the reaction will go in backward direction. (ii) n p = n r , the reaction will not be affected by increasing pressure. (iii) n p > n r , the reaction will go in backward direction. (iv) n p < n r , the reaction will go in forward direction. (v) n p > n r , the reaction will go in backward direction. ​(vi) n p > n r , the reaction will go in backward direction. While computing n p and n r only gaseous moles have been considered.
