39its relative rates of disappearence of reactants or appearence of products
answer is 2nd option. mathematically , put a negative sign before dA/dt
1yeah.. the answer is the second option
1rate of reaction is the rate of change of conc. of any if the reactants or products..
1 mole of A decomposes to give 3 moles of B in this reaction.
rate of change of conc. of A = rate of reaction.
but observe that the conc. of B increases 3 times more quickly than the conc. of A decreases. so rate of change of conc. of B is 3 times the rate of reaction.
so r=1/3 d[B]/dt
1ya it is b hey john gud explain i m now licking my lips
