Answer: a, b, d
Explanation:Physical property are measurable (or perceived) property of something observable without having to change the composition or identity of that thing.
Examples of physical properties in the context included in the question are the following: • Temperature • Solubility • Resistivity • Conductivity • Density
If the final concentration of NOBr = 0.250M
Change in concentration of NOBr = +0.250 M
Change in concentration of NO = -0.250 M
Change is concentration of Br2 = -0.125 M ( since number of moles of Br2 is 0.5 times the number of mole of NOBr)
Final concentration of NO = 0.400-0.250 = 0.150 M
Final concentration of Br2 = 0.245 - 0.125 M = 0.0120 M
Therefore;
Kc = conc (NOBr)^2/ ((conc NO)^2 ×(conc (Br2)
= (0.250²)/(0.150²×0.120)
= 23.148
= 23.1 mol/dm³
