Please solve these problems I need the correct answer ASAP

Question 1 O out of 0.34 points The gas phase irreversible reaction 2A + B =2C takes place in an isothermal batch reactor with an initial volume of 200 L and walls made out of steel. The reactor is loaded with equimolar quantities of A and B and with 200 moles in total initially. The reaction is first order with respect to A and first order with respect to B. Choose the correct value for the concentration of product when the degree of conversion is 0.8 Selected Answer: 0.7 mol/l Question 2 O out of 0.34 points The gas phase irreversible reaction 2AB - 20 takes place in an isothermal batch reactor with an initial volume of 200 L and walls made out of steel. The reactor is loaded with equimotar quantities of A and B and with 200 moles in total initially. The reaction is first order with respect to A and first order with respect to B. Choose the correct value for the concentration of product B, when the degree of conversion is 0.8 Selected Answer: 0.4 mol/L
