According to Collision Theory, the Increase in the Rate Constant

question 76

Multiple Choice

According to collision theory, the increase in the rate constant with increasing temperature is due mostly to the fact that

• A)the activation energy decreases with increasing temperature.
• B)the fraction of the collisions having sufficient energy to react increases with increasing temperature.
• C)the pressure of the reactants increases with increasing temperature.
• D)the heat change for most reactions is negative.
• E)the fraction of the collisions that have the proper orientation for reaction increases with increasing temperature.
