this is for G chem.
what is the formula for 0 order and 2 order rate constant (k) regarding to half- life. how are they related to conc and time...??

 

[ddsshin]

can someone explain why these two compounds are not same and why they are enantiomers?

zero order:
[A] = -kt + [A]initial

second order:
1/[A] = kt + 1/[A]initial

Use the integrated rate laws to solve for the half life....

what is value of sin A if sin B is 1/4. there is a right triangle. A to C is 3 and C to B is 6. A is 90 degree. C is 60 degree. thx!

Not possible. If A is a right angle and C is 60 degrees, you'd have a 30-60-90 right triangle and sin B would be 1/2 and sin A would be 1. Either the question is wrong or you're reading it wrong.
