The rate of reaction increases with increasing temperature and decreases at lower temperatures.  Eric increased the temperature on the thermostat. The rates of reaction in the room now happen more quickly or slowly?
quickly

Larger alkenes have lower boiling and melting points, so they are liquids or waxy solids at room temperature.  Tommy was assigned to work with alkene compounds for his science project. When he took them out he noticed that they were in liquid form before he even worked with them. This means that the alkenes were small alkenes or large alkenes?
large alkenes
