What is the rate equation? what are the units of rate?
rate= K (A)m(B)n A and B are reactants and m and n are the orders, K is the constant units=moldm s
1 of 6
What order do these graphs show:
a) zero, b) 1st, c) 2nd
2 of 6
How do you rearrange the rate equation to calculate the rate constant?
K=rate/ concentration of reactants(to the power of their orders), work out the units by cancelling out
3 of 6
What is the rate-determining step?
the overall rate for a mechanism with a series of steps is the slowest rate. reactants in the rate equations will be in the rate determing step
4 of 6
Rate = k[A][B] which one of these mechanisms is right:
its mechanism 2 because it has both of the reactants from the rate equation
5 of 6
Work out the orders of A and B:
reaction is second order with resecpt to A and first order with respect to B
