  • Question 9
    1 / -0

    The reaction v1A+v2Bv_1A + v_2B \rightarrow products is first order with respect to AA and zero- order with respect to BB.If the reaction is started with [A]0[A]_0 and [B]0[B]_0, the integrated rate expression of this reaction would be:

  • Question 10
    1 / -0

    Fora reaction, AB+C, A \rightarrow B +C, it was found that at the end of 10 minutes from the start, the total optical rotation of the system was 50o 50^o and when the reaction is complete, it was 100oC 100^o C Assuming that only B and C are optically active and dextro rotatory, the rate constant of this first order reaction would be ?
