Charles law states that at constant pressure, a given quantity of gas will have a volume proportional to the absolute temperature.
Explanation:
Therefore, a plot of volume versus absolute temperature should yield a straight line. And indeed it does. Real gases liquefy before absolute zero is reached, however, the value

may be extrapolated on a graph.
Answer:
Slow step is the rate determining step.
Explanation:
In general a reaction occurs in two or more elementary steps. Rate of reaction of each step is different. In chemical kinetics, rate of overall reaction is decided by rate of slowest step.
Consider the given reaction,
The given reaction has two elementary steps.
Step 1: H2(g)+ICl(g)→HI(g)+HCl(g) (slow)
Step 2: HI(g)+ICl(g)→I2(g)+HCl(g) (fast)
Step 2 is fast and completes in no time. Whereas step 1 is slow. As reaction cannot go to completion without step 1, so rate of the reaction is decided by rate of the slowest step.
Answer:
Mn= +3 charge
Explanation:
if you take what we know, and that would be the charge of oxygen, we know that oxygen has a 2- charge and there are 3 sets of O^2- so multiply the number of oxygen times the charge and you get 6-.
Next set up an equation as listed in the picture which will be 2(x)=6
and that is the charge of the Mn ion.
Answer:
55.18 L
Explanation:
First we convert 113.4 g of NO₂ into moles, using its molar mass:
- 113.4 g ÷ 46 g/mol = 2.465 mol
Then we<u> use the PV=nRT formula</u>, where:
- P = 1atm & T = 273K (This means STP)
- R = 0.082 atm·L·mol⁻¹·K⁻¹
Input the data:
- 1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K
And <u>solve for V</u>:
