In an exothermic reaction, heat is evolved, and system loses heat to the surrounding. For such system

A

`q_p` will be negative

B

`Delta_(r) H` will be negative

C

`q_p` will be positive

D

`Delta_(r ) H` will be positive

Text Solution

Verified by Experts

The correct Answer is:
A, B
Exothermic reactions are those reactions which are accompanied by the evolution of heat.
e.g., `C_((s)) + O_(2(g)) to CO_(2(g)) + 393.5 "kJ"`
`H_(2(g)) + (1)/(2) O_(2(g)) to H_(2) O_((l)) 285.8 "kJ"`
`q_p and Delta_(r) H` are negative for exothermic reaction.
