it's all true and false questions! even if you can only answer one-- i would deeply appreciate

1. the temperature of a system is inversely related to the rate of a chemical reaction. that is, as the temperature of a chemical reaction increases, the rate of the reaction decreases.
true or false

2. if reactant particles collide with sufficient kinetic energy, the collision will be effective and the reactants will convert to products.
true or false

3. in an energy diagram for a chemical reaction, the activation energy equals the overall change in energy.
true or false

4. in the following diagram, the red line describes a reaction that uses a catalyst.

true or false

the answer is c i believe

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

put the answers   and i could answer.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
