Active sites in enzymes are where substrates bind. Once they bind, a catalytic reaction occurs as a complex between substrate and enzyme is formed. Enzymes are termed as biocatalysts or simply catalysts since they speed up the catalytic reaction. After the reaction, they simply revert back to their original form, after having adjusted to fit with substrate.

A certain flexible weather balloon contains 7.4 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur

<h2>The new volume of the balloon at the top of Pikes Peak is 10.2 L</h2>

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 577.0 torr

P_2 = final pressure of gas = 400 torr

V_1 = initial volume of gas = 7.4 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 20.6^oC=273+20.6=293.6K

T_2 = final temperature of gas = 7.5^oC=273+7.5=280.5K

Now put all the given values in the above equation, we get:

\frac{577.0\times 7.4}{293.6K}=\frac{400.0\times V_2}{280.5K}

V_2=10.2L

Thus the new volume of the balloon at the top of Pikes Peak is 10.2 L
