A 684.6 mL sample of carbon dioxide was heated to 387 K. If the volume of the carbon dioxide sample at 387 K is 933.9 mL, what w
1 answer:
According to Charle's law equation, the volume of a sample of carbon dioxide will be 684.6 mL and the temperature will be 283.60 K.
<h3>Charle's law equation</h3>According to Charles' Law, the volume of a gas container with a certain amount of gas within is precisely proportional to the temperature when the pressure is constant.
<h3>Calculation:</h3> = 684.6 mL
= 933.9 mL
= ?
= 387 K
Using Charle's law equation
According to Charle's law equation, the temperature at 684.6 mL volume was 283.60 K.

<span>Chemical reactions involving only liquids will be influenced by ALL of the following EXCEPT: </span><span><span>c) size of reactant particles d) pressure of the system.
</span>Reason:
1) As per Arrhenius theory, rate of chemical reactions is influence by temperature. Mathematically it is expressed as: k = A exp(-Ea/RT)
</span>where, k = rate constant, A = collision frequency, Ea = activation energy, T = temp. From above relation, it can be seen that, chemical reactions involving only liquids will be influenced temperature.
2) Also, if know that, rates of chemical reactions is mathematically expressed as:![Rate = [A]^{x} B^{y}....](https://tex.z-dn.net/?f=%20Rate%20%3D%20%5BA%5D%5E%7Bx%7D%20B%5E%7By%7D....%20%20)

where A, B, .. are the reactants.
From above relation, it can be seen that, chemical reactions involving only liquids will be influenced concentration i.e. number of particle.
3) However, since all the reactant and catalyst used (if any) is in liquid state, particle size of same will not influence the reaction.
4) Also, since there are no gas-phase reactant, pressure will not affect the reaction.
