HXOs HZO HYOs A reaction has a rate constant of 3.0 x 102 s. Indicate the effect of the following changes on the rate constant a) Increase in T b) Addition of a catalyst c) Addition of more substrate increase decrease have no effect increase decrease have no effect) increase decrease have no effect) Indicate the effect a catalyst will have on the following values. Consider the reaction A +P increase decrease have no effect [PI at equilibrium ) energy change (AHon) of the reaction increase decrease have no effect 2N-04(9)+6H-0(9), was carried out. A system was prepared with at the eg libi is 060 M. Cal study of the system, 4NHs(g)+70(g) -3 60 M as the only components initially. A equilibrium, N O #3 60 and 0 ncentration of O2 H

Explanation / Answer

Ans 1 :

The conjugate acid of the molecule can be prepared by adding a proton to it, whereas the conjugate base can be prepared by removing a proton from it.

So here :

The conjugate acid of (C7H7)NH2 is (C7H7)NH3+

And conjugate base of HB+ is B
