40. In which of the following arrangements the given sequence is not strictly according to the property indicated against it? (1) HF < HCI < HBr < HI : increasing acidic strength
(2) H20 < H2S < H2Se < H2Te : increasing pKa values
(3) NH3 < PH3 < AsH3 < SbH3 : increasing acidic character
(4) CO2 < SiO2 < SnO2 < PbO2 : increasing oxidising power​

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.

ugh fiel iente of insistí is did kiwis jaj
