Answer 1

Answer:

it is first it it is exothermic reaction second it is endothermic reaction

Answer 2

The reaction between the action of

a. Dilute NaOH is alkaline hydrolysis

b. Dilute HCl is acidic hydrolysis

Explanation:

a.Dilute NaOH

                                                      Δ

C₂H₅-CN + H₂O + dil.NaOH →  C₂H₅ - COONa + NH₃  propanenitrile                         sodium propanoate

b. Dilute HCl

                                                       Δ

C₂H₅-CN  + 2H₂O  + dil.HCl  →   C₂H₅-COOH + NH₄Cl

                                                      Propanioc acid
