What are semiconductors ? What is the effect of increasing temperature on the conductivity of a semiconductor ?

What is the effect of rise in temperature on solubility of a gas in liquid?

What is the effect of temperature on the vapour pressure of a liquid?

What will be the effect of temperature on rate constant?

What will be the effect of temperature on a rate of a reaction?

N_2 + 3H_2 harr 2NH_3 + Heat What is the effect of increasing temperature on value of K?

Assertion: Semiconductors have -ve temperature coefficient of resistance. Reason: As temperature of a semiconductor increases, number density of charge carriers also increases.
