Consider this reaction: 2Al(s) + 3 CuCl2(aq) → 2AlCl3(aq) + 3 Cu(s) If the concentration of CuCl2 drops from 1.000 M to 0.655 M

in the first 30.0 s of the reaction, what is the average rate of reaction over this time interval?

Hello!

The average reaction rate for this reaction is 0,0038 M/s

The equation for reaction rate in this chemical reaction (for CuCl₂)  is the following one (The value 1/3 comes from the coefficient in the chemical equation for the reaction):

rate= -\frac{1}{3} * \frac{C2-C1}{t2-t1}= -\frac{1}{3} * \frac{0,655M-1M}{30s-0s}=0,0038 M/s 

Have a nice day!

How many moles are contained in 2.0 L of N2 at standard temperature and pressure.
GuDViN [60]

0.091 moles are contained in 2.0 L of N2 at standard temperature and pressure.

Explanation:

Data given:

volume of the nitrogen gas = 2 litres

Standard temperature = 273 K

Standard pressure = 1 atm

number of moles =?

R (gas constant) = 0.08201 L atm/mole K

Assuming nitrogen to be an ideal gas at STP, we will use Ideal Gas law

PV = nRT

rearranging the  equation to calculate number of moles:

PV = nRT

n = \frac{PV}{RT}

putting the values in the equation:

n = \frac{1X2}{0.08201 X 273}

n = 0.091 moles

0.091 moles of nitrogen gas is contained in a container at STP.
