Question

Question 13 (1 point) Which of the following actions would increase the rate of a reaction? Diluting the reactants by a factor of 2 Decreasing the temperature by 10°C Increasing the concentration of the reactants by a factor of 2 Increasing the concentration of the product by a factor of 2

Answer 1

answer : Increasing the concentration of the reactants by a factor of 2

explaination:

1)  
rate
$\alpha$$(C_{react.})^{n}$
when we increase the concentration of reactant it will increased the rate of reaction according to order of reaction.

2)

$K=K_{o}*exp(\frac{-E_{a}}{RT})$

rate
$(C_{react.})^{n}$

as we decreased the temperature, it will decreased the rate constant. so rate of reaction is decreased.

3)

rate
$\alpha$$(C_{react.})^{n}$

if we dilute the reactant by factor 2 , then concentration of reactant will decreased will causing decreased in rate of reaction.
