Áp dụng công thức: \(\overline{\upsilon}\) = \(\frac{\Delta C}{\Delta t}\) = \(\frac{0,22-0,1}{4}\) = 0,03 ( M/s)

Áp dụng công thức: \(\overline{\upsilon}\) = \(\frac{\Delta C}{\Delta t}\) = \(\frac{0,22-0,1}{4}\) = 0,03 ( M/s)

Biến thiên enthalpy chuẩn của phản ứng:

Δr​H2980 = \(\sum\Delta fH298o\left(sp\right)\) - \(\sum\Delta fH298o\left(cđ\right)\) = \(\left[2\cdot\right.\Delta fH298o\left(CO2+3\cdot\Delta fH298o\left(H2O\right)\right.\rbrack\) - \(\left\lbrack1\cdot\Delta fH298o\left(C2H6\right)+\right.1\cdot\Delta fH298o\left(O2\right)\rbrack\)

=\(\left\lbrack2\cdot\left(-393,50\right)+3\cdot\left(-285.84\right)\rbrack-\right.\left\lbrack1\cdot\left(-84,70\right)\right.+1\cdot0\rbrack\)

= \(\left\lbrack\left(-787,00\right)+\left(-857,52\right)\right\rbrack-\left\lbrack-84,70\right\rbrack\)

= \(\left(-1644,52\right)+84,70\)

= \(-1559,82kJ\)
