Use the periodic table to answer the following question: If 3.60 g of NaHSO, react, what is the change in enthalpy for the reaction, in kilojoules?
2 NaHSO4(s) — Na2SO4(s) + H2O(g) + SOz () AH = -231.3 kJ
Include a negative sign, if appropriate. Do not include units in your response.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
