Increase of CO2 in blood
Increases rate of respiration
Increases depth of respiration
Decreases rate of respiration
Both (A) and (B)
Increase of CO2 in blood increases rate and depth of respiration.
" The rate of photosynthesis increases with increase in intensity of sunlight till 0.02 % CO2 level and further increases with increase in intensity of sunlight only if CO2 level rises to 0.05%, " As per the video lesson and our book . But increase in CO2 level above 0.02% causes stomatal closure, which should reduce the rate of exchange of gases causing decrease in the rate of photosynthesis. Then why it's opposite happens?
Which of the following statements are in accordance with the Arrhenius equation? (a) Rate of a reaction increases with increase in temperature (b) Rate of a reaction increases with a decrease in activation energy (c) Rate constant decreases exponentially with an increase in temperature (d) Rate of reaction decreases with a decrease in activation energy
Consider the Arrhenius equation given below and mark the correct option. k=A.e−EaRT (a) Rate constant increases exponentially with increasing activation energy and decreasing temperature (b) Rate constant decreases exponentially with increasing activation energy and decreasing temperature (c) Rate constant increases exponentially with decreasing activation energy and decreasing temperature (d) Rate constant increases exponentially with decreasing activation energy and increasing temperature
