Question

give relationship formula between heat of reaction at constant pressure and volume ??​

Answer 1

$\huge{\underline{\underline{\mathbf{Answer: -}}}}$

★ relationship formula between heat of reaction at constant pressure and volume is -

∆H = ∆U + ∆Ng RT

_______________________________

Answer 2

Heat rejection at constant pressure formula is,

(Q)1-2 = mcp(T2-T1)

Q1-2 = ∆U+W1-2 general formula of gas equation.

Heat rejection at constant volume formula is,

Q1-2=mcv(T2-T1)

I hope that helps you
