With increase in temperature, the value of $$K$$ for exothermic reaction decreases because the entropy change of the system is positive

With increase in temperature, the value of $$K.$$ for endothermic reaction increases because unfavorable change in entropy of the surroundings decreases

With increase in temperature, the value of $$K$$ for endothermic reaction increases because the entropy change of the system is negative

with increase in temperature, the value of $$K$$ for exothermic reaction decreases because favorable change in entropy of the surroundings decreases

Adsorption is accompanied by decrease in ethalpy and decrease in entropy of the system

The critical temperatures of ethane and nitrogen are $$563$$ $$K$$ and $$126$$ $$K,$$ respectively. The adsorption of ethane will be more than that of nitrogen on same amount of activated charcoal at a given temperature

Cloud is an emulsion type of colloid in which liquid is dispersed phase and gas is dispersion medium

Brownian motion of colloidal particles does not depend on the size of the particles but depends on viscosity of the solution

The activation energy of the reaction is unaffected by the value of the steric factor

Experimentally determined value of frequency factor is higher than that predicted by arrhenius equation

Since $$P = 4.5,$$ the reaction will not proceed unless an effective catalyst is used

The value of frequency factor predicted by Arrhenius equation is higher than that determined experimentally

$$Al{\left( {C{H_3}} \right)_3}$$ has the three-centre two-electron bonds in its dimeric structure

$$B{H_3}$$ has the three-center two-electron bonds in its dimeric structure

$$AlC{l_3}$$ has the three-center two-electron bonds in its dimeric structure

The Lewis acidity of $$BC{l_3}$$ is greater than that of $$AlC{l_3}$$
