3. The higher the temperature is, the faster is the rate of reaction because ... more molecules collides with other molecules. less molecule collides with other molecules. molecules become smaller in size. molecules become larger. Other: 4. Why does the rate of chemical reaction increases as you increase the temperature more molecules collides with other molecules. less molecule collides with other molecules. molecules become smaller in size. molecules become larger. 5. What happens to the reaction rate if the concentration of reactants decreases? Reaction rate decreases. Reaction rate increases Reaction rate will decrease and then increase after a while.

Select all of the correct statements about reaction rates from the choices below. 1. The lower the rate of a reaction the longer it takes to reach completion.2. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step.3. Reaction rates decrease with increasing temperature.4. As a reaction progresses its rate goes down.5. Solid catalysts increase reaction rates as their surface areas increase.6. The rate of a reaction is independent of temperature.7. Reaction rates can show little change as masses of solid reactants increase.
Burning methane with oxygen is a highly exothermic reaction. Yet a mixture of methane and oxygen can be kept indefinitely without any reaction occurring. How is this possible?
