Question

State whether the following are characteristics of zero-, first-, or second-order kinetics for the reaction R ? P. If there is not enough information given to determine the order of the reaction, indicate so. (see image for choices)

3. (5 pts) State whether the following are characteristics of zero-, first-, or second-order kinetics for the reaction R P. If there is not enough information given to determine the order of the reaction, indicate so. Use the following key to indicate your answer: 0 = zero order l = first order 2 second order N/A = insufficient information (a)_The reaction rate is not affected by [R] (b)_ _A plot of In[R] vs. time is linear (c) The reaction rate increases with increasing temperature (d A catalyst can accelerate the reaction. (e) A plot of 1/R] vs. time is linear.

Explanation / Answer

(a) For zero order reaction the rate of reaction is independant of concentration of reactant

So answer : Zero

(b) the first order reaction is represented by equation

time = 1/K (ln [R0/Rt]

So on ploting a graph between time and ln[R] , the graph willbe linear

Answer: first order

c) the reaction rate increases with temperature for all endothermic reaction

so answer is : NA

d) a catalyst can accelerate the reaction for all reactions

So answer is NA

e) the second order reaction is

1/[R] = 1/ [R0] + kt

So if we plot a graph between time and 1/[R] it will be a straight line

Answer: second order
