प्रश्न
In an exothermic reaction, heat is evolved, and system loses heat to the surrounding. For such system:
(i) qp will be negative
(ii) ∆rH will be negative
(iii) qp will be positive
(iv) ∆rH will be positive
उत्तर
(i) qp will be negative
(ii) ∆rH will be negative
Explanation:
In an exothermic reaction, heat is evolved, and system loses heat to the surroundings. Therefore, qp will be negative and ∆rH will also be negative.
