The reaction between hydroxide ion, $$OH^{-}$$ and phosphinate ions, $$H_{2}PO_{2}^{2-}$$

$$H_{2}PO_2^- (aq) + OH^{-}(aq) \rightarrow H_{2}(g) + HPO_{3}^{2-}(aq)$$

has been studied by following the initial rate of formation of the gaseous product. The results are tabulated below:

What is the overall reaction order?

If temperature becomes infinite then identify the correct pattern of the plot Ink (k is a rate constant) v/s $$\frac{1}{T}$$: using arrhenius equation [$$k = Ae ^{-} \frac{E_{a}}{RT}$$]

Consider a system consisting of 1 mol of a monoatomic gas contained in a piston. What is the temperature change of the gas if q = 50 J and W = -100 J? (Given : $$R = 8.31 JK^{-1} mol^{-1}$$)

For a cyclic irreversible process, the total done by the system is:

Which of the following are not state functions?

A. q + w
B. q
C. w
D. q - w

Choose the most appropriate answer from the option given below:

A solution is prepared by dissolving solute A in solvent B, and it is found that $$\triangle_{mix}H>O$$; this indicates that:

Match List I with List II:

Choose the correct answer from the option given below:

What is the effect of pressure in the following equilibrium reaction: $$N_{2} + O_{2} \rightleftharpoons2NO$$

When a simple of $$NO_{2}$$ is placed in a container, this equilibrium is rapidly established:

$$2NO_{2}(g)\rightleftharpoons N_{2}O_{4}(g)$$

If this equilibrium mixture is a darker colour at high temperature and at low pressures, which one of these statements about the reaction is true?

Correct the order of ionic conductance at infinite dilution is:
