  • Question 3
    1 / -0

    Using the Gibbs change, \(\Delta \mathrm{G}^{\circ}=+63.3 \mathrm{kJ}\), for the following reaction, the \(\mathrm{K}_{\mathrm{sp}}\) of
    \(\mathrm{Ag}_{2} \mathrm{CO}_{3}(\mathrm{s})\) in water at \(25^{\circ} \mathrm{C}\) is :
    \(\mathrm{Ag}_{2} \mathrm{CO}_{3}(\mathrm{g}) \rightleftharpoons 2 \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{CO}_{3}^{2-}(\mathrm{aq})\left(\mathrm{R}=8.314 \mathrm{J} \mathrm{K}^{-1} \mathrm{mol}^{-1}\right)\)

  • Question 4
    1 / -0

    Identify A and B in the reaction given below.

  • Question 5
    1 / -0

    According to Einstein's interpretation of the photoelectric effect, the maximum K.E. of photoelectrons depends on ( h -W) where is the frequency of incident radiation and W is the work function. For three different metals graph plotted between maximum K/E. and the frequency of incident radiations. The three graphs obtained:

  • Question 6
    1 / -0

    For a first order reaction \(\mathrm{A} \rightarrow \mathrm{B}\), the reaction rate at reactant concentration of 0.01

    M is found to be \(2.0 \times 10^{-5} \mathrm{molL}^{-1} \mathrm{s}^{-1}\). The half-life period of the reaction is:

    The stability of an oxidation state in the lanthanides depends upon.

  • Question 8
    1 / -0

    The magnetic moment for Ni(NH3)4(NO3)2.2H2O is zero. Predict the correct formula for this coordination compound.

  • Question 9
    1 / -0

    The following plot represents the Ellingham diagram, a graph between temperature and ΔG for the formation of metal oxides. It is extremely helpful in selecting the right reducing agent for the extraction of metals.

    As per the given Ellingham diagram, which of the following conclusions is correct?

  • Question 10
    1 / -0
