The molar mass of CO is 28 g/mol while that of CO2 is 44
g/mol. Let us calculate the total moles present in the container.
total moles = [5g / (28 g/mol)] + [5g / (44 g/mol)]
total moles = 0.2922 mol
Using PV = nRT, we get the pressure:
P = nRT / V
P = (0.2922 mol * 0.0821 L atm/mol K * 323.15 K) / 0.75 L
<span>P = 10.34 atm</span>
I think it is B, but i am not sure
Cereal is a heterogeneous mixture because it is composed of many different types of ingredients.
The order of the reaction with respect to X is 2.
The statements given ;
1. As Concentration of X is in the rate law equation , changing X will have an effect on the rate of the equation.
2. Rate is proportional to X^2
So if concentration of X is doubled, then rate proportional to (2X)^2 = 4X^2
Rate therefore quadruples when X is doubled
This statement is correct
3. If we divide X/2 then the effect to the rate is (X/2)^2 = X/4 . This will reduce the rate by quarter not half . This statement is wrong.
4. If we multiply by 3
Then rate proportional to (3X)^2 = 9X^2
Rate increases by 9 times. This statement is wrong
