Answer : The correct option is, (A)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
As we are given that:
Rate of disappearing component A =
Rate of appearing component B =
Rate of appearing component C =
The general reaction is:
As per question the stoichiometry relation will be:
Now put the values of rate of following components, we get:
Thus, the stoichiometry relation is:
a : b : c = 2 : 1 : 3
Thus, the required equation will be:
Answer:
A
Explanation:
when certain chemical reactions are occurring, heat is evolved and that is what is termed exothermic reaction.
Answer:Acceleration due to gravity is 9.8m/s per second. During the next second you are already falling at 9.8m/s and accelerating to 19.6m/s. So you fall another 9.8 meters, plus 4.9 meters to account for the acceleration. During the third second, you fall 19.6 meters plus 4.9 meters to accout yet again for acceleration.
