In an endothermic reaction, the value of `DeltaH` is

A

(A) zero

B

(B) positive

C

(C) negative

D

(D) constant

Text Solution

Verified by Experts

The correct Answer is:
B
For endothermic reactions standard heat of reaction `(DeltaH)` is positive because in these reactions total energy of reactants is lower than that of products , i.e., `E_(R) lt E_(P)`
So, `DeltaH=E_(P)-E_(R)=+ve`
