What causes an increase in the reaction rate between molecules

2 answers:

8 0

molecules collide more frequently.

Chemical reaction mechanisms are based in the collision of molecules with certaing level of energy. More collisions implies grater probablity of reaction.

Increasing temperature, increasing pressure of gaseous reactants, increasing concentration of solutes, adding a catalyst are all ways to increase reaction rates.

What is NOOH in amino acid?

mihalych1998 [28]

<span>-NH2 or, in its ionized form, -NH3+. Amino groups are the functional groups that bestow the "amino" in amino acid. They also readily ionize, gaining a proton (hydrogen ion), and thus serve as weak bases.</span>

What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su

anastassius [24]

Answer:

$V=27992L=28.00m^3$

Explanation:

Hello,

In this case, the combustion of methane is shown below:

$CH_4+2O_2\rightarrow CO_2+2H_2O$

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

$n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4$

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

$PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3$

Best regards.
