The reaction 2 NO(g) + Cl2(g) → 2 NOCl(g)
was studied at −10°C. The following results were obtained, where the rate of the reaction is the following.
rate = − d[Cl2]/dt
What is the value of the rate constant?

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

The tendency of water molecules to stick together is referred to as a) adhesion b) polarity c) cohesion d) transpiration e) evaporation
