Calculate the reaction quotient Qp for the following redox reaction: 14H+ + Cr2O72- + 6Cl- ----> 2Cr3+ + 3Cl2 + 7H2O The reac
stich3 [128]

Answer:

Value of Q_{p} for the given redox reaction is 1.0\times 10^{-8}

Explanation:

Redox reaction with states of species:

14H^{+}(aq.)+Cr_{2}O_{7}^{2-}(aq.)+6Cl^{-}(aq.)\rightarrow 2Cr^{3+}(aq.)+3Cl_{2}(g)+7H_{2}O(l)

Reaction quotient for this redox reaction:

Q_{p}=\frac{[Cr^{3+}]^{2}.P_{Cl_{2}}^{3}}{[H^{+}]^{14}.[Cr_{2}O_{7}^{2-}].[Cl^{-}]^{6}}

Species inside third braket represent concentration in molarity, P represent pressure in atm and concentration of H_{2}O is taken as 1 due to the fact that H_{2}O is a pure liquid.

pH=-log[H^{+}]

So, [H^{+}]=10^{-pH}

Plug in all the given values in the equation of Q_{p}:

Q_{p}=\frac{(0.10)^{2}\times (0.010)^{3}}{(10^{-0.0})^{14}\times (1.0)\times (1.0)^{6}}=1.0\times 10^{-8}

A scientist stores a very large number of particles in a container. In order to determine the number of particles, the scientist
Leni [432]

When the temperature and the volume of the gas stored in the container are high then the number of the moles will be measured accurately. Thus, options A and B are correct.

<h3>What is the ideal gas law?</h3>

The ideal gas law is the establishment of the relation between the elements like the moles, pressure, temperature, and the volume of the gas containing the particle.

The ideal gas states:

PV = nRT

With an increase in the temperature, the number of particles that collides increases as the kinetic energy increases. The particle of the container is more when the volume of the gas is more.

Therefore, in options A and B high temperature and volume increase the accuracy.
