Question

just answers please, thanks a bunch

Shown below are the initial conditions for four separate experiments for the reaction A+B2-> C. What is the rate equation for this reaction? Relative initial rate = Orate-k[A] Orate-k[B2] rate=k[A][B,12 o'rate-k[A]2[B2]2 Orate-k[A]2B2]

Answers

Question 1

Rate equation for the reaction A + B2 $\rightarrow$ C, is

rate = K [A]2[B2]

• Representation of rate of a reaction in terms of concentration of reactants is known as rate law or rate equation or rate expression.rate law is the expression in which reaction rate is given in terms of molar concentation of reactants with each term raised to some power , which may or may not be the same as the stotiometric coefficient of the reacting species in a balanced chemical equation.
• A + B2 $\rightarrow$ C, this raction is not balanced .balaced equation is  2A + B2 $\rightarrow$ 2C
• so, rate = K [A]2[B2]

Question 2

Answer : 2.0mol L-1min-1

here one part of nitrogen reacting with 3 parts of hydrogen . so if 6 mol L-1min-1 H2 is consumed ,then 1/3rd of N2 will consumed .

so answer is 6/3 = 2

Question 3

Answer : first order

order of a reaction is the sum of the powers of the concentration terms in the rate law.

to find out the overall order of a reaction having two or more reactants, add the individual order with respect to each reactant.

here order with respect to A = 0 and order with respect to B = 1

therefor, overall order = 0+1 = 1 thus it is a first order reaction.
