Elementry Reactions

Which of the option(s) regarding true/false nature of the statement is/are correct ? S-1 out of all colligative properties, osmotic pressure is easiest to determine experimentally. S-2 Chemisorption is a multilayer process. S-3 Solubility of gases in water increases with increase in temperature S-4 Addition of NaCl can cause coagulation in both + vely charged and - vely charged sols. S-5 Enzymes catalysed reactions are elementry reactions. S-6 NaCl crystal shows Frenkel defects.

The rate law for a reaction is Rate = k[A]^(1//2)[B]^2 Can the reaction be an elementry reaction. Explain.

Statement: The elementary reaction is single step reaction and does not possess mechanism. Explanation: An elementry reaction has order of reaction and molecularity same.

The reaction 2NO+O_(2)rarr2NO_(2) proceeds in two steps. If one elementry reaction is NO+O_(2)rarrNO_(3) , write the second elementary reaction. Write the rate law of the reaction

For an elementry reaction aArarr product, the graph plotted between reaction log[(-d[A])/(dt)] vs. time gives a straight line with intercept equal to 0.6 and showing an angle of 45^(@) with origin, then:

For an elementry reaction 2A+3B to 4C+D the rate of appearance of C at time is 2.8 xx10^(-3) " mol " L^(-1)S^(-1) . Rate of disappearance of B at 't' , will be
