Question

chapters 1 - 2 - 3 and 4
decreased temperature
increased temperature
absence of enzymes
decreased concentration of reactants
presence of catalysts
increased concentration of reactants
rate of reaction decreases (1/2)
rate of reaction increases (2/2)

Explanation:

Temperature, reactant concentration and presence of catalysts/enzyme affect reaction rate. Lower temperature, lower reactant concentration and absence of catalysts decrease rate. Higher temperature, higher reactant concentration and presence of catalysts increase rate.

Answer:

Rate of Reaction DECREASES (1/2): Decreased temperature, Absence of enzymes, Decreased concentration of reactants
Rate of Reaction INCREASES (2/2): Increased temperature, Presence of catalysts, Increased concentration of reactants
