For the ring opening reaction of cyclopropane to propene at 25°C, the pre-exponential factor is $4.3 \times 10^{15}\ \mathrm{s^{-1}}$. The entropy of activation (in $\mathrm{J\,K^{-1}\,mol^{-1}}$, rounded off to two decimal places) is ____ (Given: $h = 6.626 \times 10^{-34}$ J s; $k_B = 1.38 \times 10^{-23}\ \mathrm{J\,K^{-1}}$; $R = 8.314\ \mathrm{J\,K^{-1}\,mol^{-1}}$)
