Two flip-flops are connected as shown below. The delay represents wiring delay between the two clock inputs, which results in clock skew. This can cause possible loss of synchronization. The flip-flop propagation delay from clock to Q is 10 ns < tp < 15 ns, the set-up an...

For a one step reaction, the activation energy for the forward reaction is 40.0 kJ/mol and the enthalpy of reaction is -20.0 kJ /mol. Which statement below is true? a. The activation energy of the forward reaction would be affected to a greater extent than the activation energ...
A + 2 B = C + D describes an elementary reaction, which takes place in a single step. Thus, the rate law must be a) rate = k (A)^2 b) rate = k (B)^2 c) rate = k (A) (B) d) rate = k (A) (B)^2 I think its D because there are 2 moles of B and 1 mole of A. Do you agree with my ans...
The decomposition of hydrogen peroxide in solution and in the presence of iodide ion was studied in laboratory, and the following mechanism proposed based on the experimental data. H2O2 + I - = H2O + IO - (slow) H2O2 + IO - = H2O + O2 + I - (fast) Which one of the following st...
So based of the rule of thumb, its going to be 5 times faster. Also how can I use Arrhenius equation without the rate constant (k)?
A particular reaction has an activation energy of 51.6 kJ/mol-rxn. How much faster is the reaction at 50 oC versus 25 oC? a. 2 times b. 5 times c. 3 times d. half as fast d. 20% as fast I think it would be A??

1) cscθ = (-5/3) , θ is in third quadrant 1/sinθ = (-5/3) => sinθ= -3/5 θ= -36.8699 θ is in third quadrant so θ = 36.8669+180 = 216.8669 tan2θ = tan2(216.8669) = 3.42724 = 24/7 answer : c
1) cosθ=0.8 , θ is in fourth quadrant θ= cos^(-1)0.8=36.86989765 + 270=306.87 so , sin 2θ= sin2(306.87)= -0.96 answer : a
